Last updated on JANUARY 21, 2011

Applies to:

Oracle Text - Version: 10.2.0.1 to 11.2.0.2 - Release: 10.2 to 11.2
Information in this document applies to any platform.

Symptoms

While performing fuzzy queries with wildcard search terms, for some terms, the result hits for exact matches have lower score than hits that are more distant matches to the input term.
However, the score value is correct when the query is performed without wildcards, for example:

'fuzzy(%KUNIBERT%,60,100,weight)'

versus

'fuzzy(KUNIBERT,60,100,weight)'
