The Spire Project: Searching The Web The Spire Project searching the Web. The Articles covers search engines, search options like truncation field searches, and other webrelated search tools like the Scout archive. When searching for a topic with precise descriptive terms, use a large international search engine. Google now accepts link and site field searching with mixed results. http://cn.net.au/webpage.htm
Extractions: W ebpages are often of unknown age, of only guessed at quality and potentially the easiest information to retrieve. There are many points of entry to web resources but search tools differ. Try to match your search tool to your question. To start, you will need to learn something of the different tools - introduced below - and four basic search techniques: Boolean Proximity Field Searches Truncation I nternet Global Search Engines When searching for a topic with precise descriptive terms, use a large international search engine. Always place the Boolean symbol before each search word (like this: ) to insist all words appear in the results. Quotes keep words together ( ). These two simple steps dramatically improve results. Keep adding words and search limits until the number of matches is reasonable. Altavista , among other tools, has a very large fast search engine. Allows for
Keyword Searching And Truncation heading in the thesaurus is not specific enough. For example, to search the topicof spontaneous hypertension For example, in MEDLINE searching Gilles de la http://www.health.library.mcgill.ca/eguides/truncat.htm
Extractions: Keyword Searching / Truncation In almost all databases, including MEDLINE, a topic can be searched in one of two ways: by using the thesaurus, often referred to as the "controlled vocabulary", of the database. This method of searching is known as "subject searching". Subject searching generally yields more precise and relevant results, consequently you should always attempt to conduct a search by subject Many databases on the McGill Libraries' Ovid system use a controlled vocabulary to index articles and to assist users in their search for appropriate terminology. In MEDLINE, the controlled vocabulary is known as MeSH by searching the non-subject fields such as title and abstract. This method of searching is known as "keyword" or "textword" searching. Keyword searching, while more comprehensive, generally tends to be less accurate, and yields more irrelevant results than a subject search since words or phrases may have more than one meaning
Searching Specific Fields For A Query Word searching specific Fields for a Query Word. When searching a databasein which records have been organized into fields, you can formulate http://uscode.house.gov/data-src/help/htmlsrc/fld1op.html
Extractions: When searching a database in which records have been organized into fields, you can formulate queries that consider only a specified field or range of fields within each record. Moreover, you can search particular fields for terms that match a specified alphanumeric value or for fields that fall within a specified range of values. You can use the word-level field restriction operator the colonto search one or more fields for a particular query term. Syntax: word where word is the query term to be sought and field specifies one or more fields to which the search will be restricted; if you specify multiple fields, their names must be separated by commas. You can use partial field names with this operator. The word-level field restriction operator will be distributed through scope of operation delimiters . For example, the following query: (Harding AND Gillooly):defendant is equivalent to: Harding:defendant AND Gillooly:defendant Examples: Renfield:name,supervisor Abdul:author AND Necronomicon:title The first query will retrieve records that contain Renfield in either of the name or supervisor fields.
Searching Indexes And Databases Also, not being familiar with the specific vocabulary or subject terms used for thetopic can present get around these problems when searching for information http://www.wesleyan.edu/libr/tut/rst4.htm
Extractions: Searching Indexes and Databases Searching for information on one particular topic is relatively easy: just look up the term you are interested in. But if you want to find sources that discuss a particular set of different topics, it can be time consuming to look up and make lists of all the sources on each individual topic and then pick out those sources which are on all the lists. Also, not being familiar with the specific vocabulary or standard subject terms used for the topic can present difficulties when you do not know what terms to look up (e.g. does the index use "elderly," "senior citizens," or "aged"?). But there are a few tricks to get around these problems when searching for information on a computer database. Here are some common searching techniques which offer powerful tools for quickly and accurately broadening, narrowing, or refining your search on a computer database. Most online indexes and databases have at least some of these search options, but there are often differences in how to use them, so read the help screens for the database you are using.

DUMCL - 12 Tips To A Better MEDLINE Search experts reading each article and assigning specific terminology (Medical Searchingby textwords (or keywords), on the other word(s) are actually a topic of the http://www.mclibrary.duke.edu/respub/guides/ovd12tip.html
Extractions: MEDLINE includes over 9.5 million citations, but not all of them will be relevant to your information needs. Think about your topic and what will provide the best information. Be specific and break it into the important parts, such as the problem or subject group, intervention, outcome, and/or type of study. Example : You need information on clinics for congestive heart failure patients and whether or not they can reduce the rate of readmissions or hospitalization. The important concepts are congestive heart failure and related conditions outpatient clinics and hospital readmissions . You may not need to use all the concepts in the search strategy, but they will be useful in identifying the most appropriate articles. MEDLINE is a very structured database, with subject experts reading each article and assigning specific terminology ( Medical Subject Headings or MeSH ) to describe the content of the article. Searching by textwords (or keywords), on the other hand, is a search for the occurrence of the exact word(s) in the title or abstract, which does not guarantee that the word(s) are actually a topic of the article. The mapping feature in Ovid is designed to help you identify the appropriate subject headings or MeSH terms.

Much valuable information can be found on the WWW. Much useless or misleading information can also be found on the WWW. You should look for information on the WWW when: You need very current information You want information direct from the government any level of government You want information direct from a company or an organization When determining whether to use information found on the WWW consult the section of this guide entitled Evaluating the information you have located and pay particular attention to the criteria for WWW information. Helpful tools in locating information on the World Wide Web: It is advisable to choose one or two search tools and to get to know them well so that you can utilize them when you need to search the World Wide Web. Most of these search tools change frequently so you will have to visit your chosen tools periodically to keep up with them. All of these search tools have help screens to answer questions specific to that tool. Directories are collections of WWW sites which have been arranged hierarchically under broad subject headings through the efforts of human beings who are trying to bring some order to the information available on the WWW. As you go down the hierarchy, each level of subject headings gets more specific until you find the heading closest to what you need. Using a directory is a somewhat organized approach to finding information on the WWW.

However, for your convenience, links are cross-referenced under both Topics and Categories. Resources are grouped with related subjects, rather than alphabetically, but issues often have many dimensions (such as both educational and psychological implications), so there might be more links on a subject than those found in just one place.

Extractions: The tremendous growth in the price-performance of networking and storage has fueled the explosive growth of the web. The amount of information easily accessible from the desktop has dramatically increased by several orders of magnitude in the last few years, and shows no signs of abating. Users of the web are being confronted with the consequent information overload problem. It can be exceedingly difficult to locate resources that are both high-quality and relevant to their information needs. Traditional automated methods for locating information are easily overwhelmed by low-quality and unrelated content. Thus, the second generation of search engines will have to have effective methods for focusing on the most authoritative among these documents. The rich structure implicit in the hyperlinks among Web documents offers a simple, and effective, means to deal with many of these problems. The CLEVER search engine incorporates several algorithms that make use of hyperlink structure for discovering high-quality information on the Web. Ongoing work in the Clever project focuses on higher-level applications based on the basic Clever engine described in the publications below. There are a number of emerging new directions within the CLEVER project.
