// Note: This function is a hack to fix a word breaker issue. The word
|
|
// breaker does compund word breaking for some languages, such as
|
|
// German. For example, "tes" is broken into "tes" and "1".
|
|
// "tes" get a synonyn "t" and "1" gets a synonym "es". This is a
|
|
// result of a hack in the infosoft word breaker. The "1" is a place
|
|
// holder and is thrown out in a non prefix match phrase to capture
|
|
// the case ("tes" | "t") "es". However, this breaks the prefix
|
|
// matching scenerio. Noise words are not thrown out in a prefix
|
|
// matching (GENERATE_METHOD_PREFIX) query, "tes*" becomes
|
|
// (tes*|t*) (1*|es*). In this case, tes*" is not a match unless
|
|
// it is followed immediately with a 1* or es*, e.g. "test case"
|
|
// is not a match whereas "tested 1000 times" and "testing especially"
|
|
// are matches. The hack here is to Or a CWordRestriction of the
|
|
// originally phrase without word breaking. This hack works fine,
|
|
// if the original phrase is a single word. It will not work in the
|
|
// multiple word case.
