[Framers] Searching for content in FrameMaker files

[Austin Meredith]

   I don't seem to be able to persuade the File Explorer of Windows 10 to
   find Boolean content inside FrameMaker2015 files. I've tried all the
   obvious tricks such as making certain that the file suffixes ".fm" and
   ".frame" are included in the indexing list, and deleting and rebuilding
   that indexing list. File Explorer will find the name "Thoreau" if it is
   part of the FrameMaker file's filename such as "ThoreauINDEX.fm" and
   will indeed find the name "Thoreau" when it is *inside* a '.txt" or
   other file, but refuses to find the name "Thoreau" for me when it is
   inside a ".fm" or ".frame" file. What am I doing wrong? -Austin
