No problem. That’s how I have now gone about it.

I didn’t test it in a DB, sorry ’bout that.

 

I think others are on the right track here, using SQL for the AND functionality:

 

‘Select *

FROM [TABLE]

WHERE [regex search 1]

AND [regex search 2]

AND [regex search 3]
....’



Thanks,

Hi Andrew,

 

Thanks for the reply.

 

I tried the query, but it produced an error “invalid regular expression: quantifier operand invalid”.

 

Also, what would be the regular expression if you want to check whether all the words were in the field where you had say 10 words/phrases you wanted to check for?

‘(*\mtext1\M*\mtext2\M)|(*\mtext2\M*\mtext1\M)’

Thanks,

If I wanted to search for whole words in a field I would use something like:

 

Select * from mytable where myfield ~* ‘(\mtext1\M) | (\mtext2\M)’

 

This would find all instances of myfield containing either “text1” or “text2”.

 

I can’t figure out how to search myfield for all instances which contain “text1” AND “text2”.

 

In other words | is the OR operator. What is the AND operator. Tried + and whilst that executes, it doesn’t return matching fields.

 

Thanks

 

Mark
