Advanced Searching Tools
With easily composed natural language queries and relevance ranking, you will be put in touch with more relevant
documents in a shorter period of time. Since overall searching time is reduced, you will be able to take advantage of
several powerful feedback tools that PLWeb Turbo makes available.
PLWeb Turbo promotes spontaneity by allowing an interactive search process. When you see results from one search, they
may inspire new ideas for other information that you didn't originally know you wanted. You can then use PLWeb Turbo's
tools to incorporate these new ideas into your query. As you combine methods to refine your query, you quickly get
closer to the information that is most important to you. You will find that feedback searching usually yields more
satisfactory results than traditional Boolean strategies.
This tool lets you search based on a general idea. In cases where you can't immediately articulate your information
needs, you can perform a concept search and build on the results.
PLWeb Turbo features tools called advisors, which serve as online assistants. As part of the feedback searching process, you
can use the advisors to gain added insight into the nature of a database's contents.
The Relate Advisor can suggest appropriate search terms that you might never have considered. It produces a list of
words that, in the context of the database, are related to the words in your current query.
The Dictionary Advisor can verify the existence of a query word and/or its variants within a database. With this
advisor, you can decide if a word might yield good results, or if it should be excluded.
The Fuzzy Match Advisor scans the database for words with spelling similar to that of a query term. It can identify
correct spelling--if you're in doubt about yours--and instances where scanned material has been incorrectly
interpreted during OCR (optical character recognition) processing.
When formulating queries, you can take advantage of the wide variety of operators supported by PLWeb Turbo. Using
operators, you can impose Boolean logic to produce specific search results, find occurrences of
adjacency/proximity of search terms, search for exact phrases, impose algebraic logic on complex queries,
restrict a search to one or more fields, etc.
For databases containing records with fielded information, you can perform field-restricted searching, wherein
PLWeb Turbo's search considers only the contents of one or more specified fields.
