Fuzzy and proximity searches

A fuzzy search looks for character sequences that are not only the same but similar to the query term. Use the tilde symbol (~) at the end of a term to perform a fuzzy search. For example, the following query finds documents that include the terms analytics, analyze, and analysis:

analytics~

An optional parameter can be used to specify the required similarity. Specify a value greater than 0 and less than 1. The value must be preceded by a 0 and decimal point, for example, 0.8:

analytics~0.8

A value closer to 1 matches terms with a higher similarity. If the parameter is not specified, the default is 0.5.

A proximity search finds documents that contain terms within a specified number of words of each other. Use the tilde symbol (~) to perform a proximity search. For example, the following query finds documents that contain “IBM” and “WebSphere” within seven words of each other:

"IBM WebSphere"~7

Proximity search is supported for individual terms, not phrases. Also, a word after a sentence break is considered 10 positions apart from the last word of the previous sentence.
