parameter for text
You will need a separate textbox for each pattern for which the user wishes
to search. This of course, will be problematic. If you provide two textboxes, the users will tell you they need a third. After you provide that one, they will of course demand a 4th ... ad nauseam You might consider a keyword-table approach, especially if users will only ever be searching for whole words. This will involve creating a table that includes the key field(s) from the first table, plus a single field for the keywords. You would probably want to exclude "nuisance" words from the keyword list: "the", "to", "a", etc. Including them would cause too many unrelated results to be returned in searches (Google has a similar approach). The result would be like this: Sourcetable: ID textfield 1 A phrase with several words Keywords: ID Keyword 1 phrase 1 several 1 words Your criterion would be in the ID field and would look like this*: IN (Select ID FROM keywords WHERE "," & [txtwords] & "," LIKE "*," & [keyword] & ",*" ) *This is untested and was included only to provide a general idea for how to approach this. sebastico wrote: Bob The field I'm searching has one or more words. Can I enter one, two or three words or do I have to use more txtboxes? Thank you for your help "Bob Barrows" wrote: sebastico wrote: In Access 2003. In a form I have a parameter to search for a word at a a time Like [Froms].[Form].txtWords]&"*" which works well. . In order to enter more than two oarameter separated by commas in txtwords I have been tryin the Str function like this "Instr([txtWords])" "Instr[txtWords]" The query displays no records at all. Could you suggest me how to do it I don't think it's doable. If the field you were searching contained only single words and you were trying to match the entire word, the Instr solution can work. But since you are doing pattern-matching using LIKE, there is no way to search for multiple patterns without using OR to combine them: Like [txtword1] & "*" OR Like [txtword2] & "*" It appears you will need to provide multiple textboxes and instruct the users to enter a single search pattern into each. -- HTH, Bob Barrows . -- Microsoft MVP - ASP/ASP.NET - 2004-2007 Please reply to the newsgroup.
