in reply to Comparing sets of phrases stored in a database?

Interesting question.

In PostgreSQL there are some text tools that may already be adequate for such a database:

The built-in full-text search (includes indexing, parsing, stemming, ranking). [1]

The extension pg_trgm (trigrams). Can be used to index, provides similarity functions. [2]

The extension fuzzystrmatch (with soundex, levenshtein etc.). [3]

[hippo]: :-D
[Eily]: you mean a dll where the SW was written in perl? That sounds unlikely
[muthusathish]: please help me regarding this
[hippo]: Easier just to go and look at the source, no?
[Eily]: mostly because perl isn't compiled in the usual sense of the meaning, you can't execute the opcodes directly, you need the perl engine
[muthusathish]: i dont have the environment too, but i need to get the logics so that i can re-wite
[Eily]: what makes you think your dll is "perl based" ?
[muthusathish]: i dont have source code too
[muthusathish]: it is used in VB 6 appln, while debugging is getting error
[hippo]: Somebody has. Ask the author.
