optimize and filters with RH11

• does anyone know if there is a way to optimize the number of files produced when generating an output in HTML5 (with RH11)??  The project that I have to compile is composed of 19 different merged projects and the number of total files (although the minimum size) becomes really huge...

• another question...someone know a way to insert the search filters in the generated project? i found an example here...

http://www.wvanweelden.eu/blog/2014/02/16/adobe-robohelp-filtering-webhelp-search-results but this method seems to be based solely on the recognition of a tag associated in the title of the topic, whereas I'd need a method to insert an equivalent tags within the text topic.

thx
