**hi i want use $strstr for multi strings infact i want multi strings search on filename. for example filename 1 is: abcd filename 2 is: qwer filename 3 is: zxcv** my incorrect $strstr is: $strstr(%\_filename%,'abcd' OR 'qwer' OR 'zxcv') please correction that tnx ---

The comparison syntax would be: "$ifgreater($strstr(%\_filename%,'abcd'),0,yes,no)" IS yes you would have to compare each substring separately but you can compose them to "$ifgreater($strstr(%\_filename%,'abcd'),0,yes,no)" IS yes OR "$ifgreater($strstr(%\_filename%,'efgh'),0,yes,no)" IS yes ---

> [@peymanch](#): > > **no dear friend it's not work i want use multi string in format value and this is not supported IS and OR!** That is why it would be much better if you said that in the first place. You misguided me by introducing the OR. Right now I fear that you muck about with the filename instead of using the metadata of the fields to create a filename. Anyway: $ifgreater($strstr(%\_filename%,'abcd'),0,yes,no) has everything you need: instead of "yes" or "no" insert that what you want to get in case it matches or it does not. ---

It should work the way you have described your need. Do you need a filterstring to display all related files? ... or ... Do you need a formatstring to set a filename or tagfield value?
