When using windows search (using windows explorer) Sumatra PDF has an iFilter that allows searching text content of the pdf, but any tags used are not shown.
For example, if you type “tag: SearchableDOC” in Windows Search, with the Adobe iFilter, it will show, but not Sumatra (And the Adobe iFilter is only available to 64 bit, which causes problems in Enterprise environments that are reluctant to upgrade)
