Hi all, I need to support query expressions like *xyz and possibly *lmn*. The former can be done with high search efficiency by storing (delimited) reversed tokens and the latter by storing all (delimited) rotations for each token. However, both of these techniques have high index overhead, the rotations being considerably worse than just the reversals. In principle, nothing is needed for the reversed or rotated tokens others than the tokens themselves as their position and term vector information is the same as the base token.
Have others found a better solution for this? If not, it occurs to me that one simple and substantial optimization is to support a token filter for term vectors, i.e. pass tokens through an additional filter for addition to term vectors. Unless there is a better solution, I'll post such a patch. Thanks for any advice, Chuck --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
