As anyone had this problem?

I have created several tables similar to product book & product music, I have created several filters which search the tables these work great but I cannot get sensible metatag data with the searches, all I get is category names which are no use.

I'm sure it could be done as the manufacture search in the default load of Zen cart works, I'm guessing it looks at the manufactures tables & loads that info.

I tried to clone the manufacturer search itself but it did not work as a new index filter.

Ver 1.39 working only on local system at present.

Any help in which files to search would be appreciated
