An integrator may customize the program to allow for "fuzzy" phrase searches. "Fuzzy" phrase matching allows you to search for a phrase even when you don’t know the exact order of the words in the phrase, or when one or two words fall between the first word and any other word in the search phrase. For example, a fuzzy search on the phrase "Jane Smith" would locate:
Jane Ann Smith
Jane and Bob Smith
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
Search is narrowed by:
- setting a lower number of wildcard words to use in the wildcard expansion
- using the Advanced Search tab to choose specific expansions
Search is widened by setting a higher number of wildcard words to use
Search time is generally faster because no semantic expansion is performed on wildcard words; however, if wildcards are used too broadly (such as co*), or if you set the number of wildcard words very high, the search time can be long and the response too large to be useful
Most effective when you are:
- searching for a proper name that you can’t remember how to spell
- searching for multiple terms that have several similar characters (such as model "C1050," "C1051," and "C1052")
- not sure what form a particular word takes in the database, and want to ensure that all forms of it are found
|@||match exactly one alpha character||c@re|
|#||match exactly one numeric character||#600|
take the next character literally; not as an operator
NOTE: This operator works only if the character following it has been indexed for searches.
|*||match any character(s) (including nothing)||pharma*|
|?||match exactly one character||la?er|
|[ ]||search expression; can include a hyphen to indicate a range of letters or numbers; will match only one character within the brackets||A[1-5]|
|[^]||match any character except the next character||199[^1-3]|
