Not exactly. You can search in the *indices* for all Info files using
the index apropos feature, either with

$ info -k term

which spits out a list of matches.

Or run

$ info

followed by M-x index-apropos RET term RET

Note that the manual indices are just whatever the document author
decided to add, so you are relying on them having added a relevant
index entry.

Alternatively, you can use grep (the low-tech solution):

for f in /usr/share/info/*info*gz ; do echo ============ $f
============ ; gzip -cd $f | grep foo ; done
