are there any cases in which you ever want to search the field for tokenized values? if not, then you can just use an analyzer that knows about this special field and "tokenizes" any value it gets into a single token that is an exact match. if you sometimes need exact matches, and sometimes need "ord" matches (for hte sake of argument let's assume your tokens are simple shitespace seperated words) then you're going to need somewhat of knowing which case you wnat when you parse the query -- the easy way to go is with a seperate field like Erik described. if you have some other usecase, then you can index the field using an analyzer that generates a single unparsed "token" for hte whole string followed by some marker token that isn't likely to appear in your data (ie: the token "_BOOYA!_" would probably work), followed by the more conventional tokens -- given the first of those tokens a very high positionalIncriment. Then if you want an exact match, your custom query parsing code could generate either a Phrase or Span query containing a single Term for your input, followed by the marker Term (ie: "_BOOYA!_"). a "regular" toekn based search would work just as it did before. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
