Re: OR-searching

It keeps the original formatting.

texte = >>> try [search db=group.db&woGROUP_IDdatarq=1&woGROUP_IDdatarq=2] >>> in a database like this: >>> >>> GROUP_ID >>> 2 >>> 12 >>> 206 >>> 422 This search will fail because there are two parameters targeting the same database field. Please remember, it is NOT ALLOWED to search on a 'database' field with more than one parameter! If you need to search the same database field with more than one parameter, you MUST use the group field technique, like this:[search db=group.db &group1field=GROUP_ID &group2field=GROUP_ID &wogroup1datarq=1 &wogroup2datarq=2]... because this is not actually searching on a 'database' field, it is actually searching on a 'group' field which you have created dynamically within the search context itself.The above search will retrieve all 4 records because either 1 or 2 appears in all of them. But if you want to retrieve only records which have *exactly* 1 or 2 in the GROUP_ID field (which in this case is only the first record) you must ALSO add the ww parameter to each search field, so the search context looks like this:[search db=group.db &group1field=GROUP_ID &group2field=GROUP_ID &wogroup1datarq=1 &wogroup1datarq=2 &group1word=ww &group2word=ww]Please note, I have added extra cr's to this code for clarity, so be sure to remove them if you're going to copy/paste these examples.================================ Kenneth Grome, WebDNA Consultant 808-737-6499 http://webdna.net ================================------------------------------------------------------------- Brought to you by CommuniGate Pro - The Buzz Word Compliant Messaging Server.
