Help With Searching

Keyword Search

A primary query mode that accepts queries constructed with Boolean logic. The default operator between query terms is AND; thus a query for term1 term2 is logically equivalent to a query for term1 AND term2.

    The stemmed version of the query terms are used to compare against stemmed terms in the index.  For example, the query term territorial could        be stemmed to the base term of territor and the query term legislature could be stemmed to the base term of legislat As a result, a search                 for territorial legislature could match results with terms such as territory legislative.

    No semantic term expansion occurs in this type of search. For example, a search for the term intelligent would not match the indexed term             smart. 

    Concept Search     

    A primary query mode that accepts plain English queries without operators.  Semantic expansion is automatically performed on all query words.    For example, a search for the term intelligent would find documents containing the term smart.


    Pattern Search

    A primary query type that processes plain English queries, but tolerates spelling differences in either the body of the text or the queries.  Pattern     expansion is automatically performed on all query words to the level specified in the “Pattern Search, Similarity Setting” preference.


    Exact Search

    A primary query type used to find exact matches for all query terms.  The query terms are not stemmed or expanded in any way.  Queries using        Boolean logic are accepted. The default operator between query terms is AND; thus a query for term1 term2 is logically equivalent to a query for     term1 AND term2. 

    In the Exact search mode, a search for territorial will match only the word territorial.  Thus, a search for territorial legislature would find                   documents containing those two exact terms. However, some of the results may also contain stemmed versions of these terms, but they would        not be considered a matched term, and would not be highlighted as such.  To find all documents that contain the exact terms territorial legislature     but do not also contain the exact terms territory legislative, use Exact search for territorial legislature -territory -legislative.  Note: the order of the     query terms does not matter in these examples.

Wildcard Search

    For searches using wildcard characters, use the “Exact” search mode.

    For the most relevant results, if you are looking for a “hit” within a field, search within the field, not within the “Search For” box.

A query that substitutes part of a word, name, or number with a wildcard character (*, ?, [search expression], _, @, #, \, ^ ) to substitute for unknowns in the search terms or database, or to search for multiple terms; wildcards can be used in Concept or Boolean mode (not Pattern), in full text search or field entries, in multiple words, and even multiple times in one word.
