Hi, I'm having a problem when I want to search a phrase containing a stopword.

Is there any way to search a term like "BOB IS TALL" (IS is a stopword) and get all the documents that contain only "BOB IS TALL" and not phrases like "BOB WAS TALL" that It's not the idea to get?.


Thank's in advance...

No, not with Oracle Text and IS in the stoplist. It will return BOB any_one_word TALL. You can remove IS from the stoplist, but that usually causes more problems than it solves. You can search using INSTR instead of CONTAINS, but then you would not be able to use the text index and other text features. It seems like kind of an unusual requirement to need to find "BOB IS TALL" and not "BOB WAS TALL", but perhaps this is a simplification of a more complex problem.

Hi, that's what I thought...removing the word from the stoplist would cause a lot of problems because this time the problem is with that word, but tomorrow they'll need to search using an another stopword and I'll be in the same situation.
"Bob is tall" is just an example, actually my stoplist is in spanish and the phrase that made the user complain was "Ciudad de Asuncion" ("de" is a stopword that in this case would mean "of").
This matter should be cataloged as "not fixable" with Oracle Text????.

Thank's Barbara for your help.
