The Comment field provides a user-visible description of the app,
which usually contains generic words ("and", "or", "not", "is", ...)
that add noise when used for search.
It made some sense to match against the field as a fallback for
Keywords, before that key was well established. However that key
has been around for years now, so hopefully every app where additional
terms are helpful uses it by now.
With that, the downside of added noise outweighs the benefit, so
it's time to stop matching on comments.

*
|
||
* In short, we keep around arrays of results that we expand as needed
|

* (and never shrink).
|
||
*
|
||
* static_token_results: this is where we append the results for each

*
|

* found for each term)

*

* static_total_results: this is where we build the complete results

||
* across all directories (which is a union of the matches found in

* The app_names that enter these tables are always pointer-unique (in

* the sense that string equality is the same as pointer equality).

* This can be guaranteed for two reasons:
|

*
|
||
* - we mask appids so that a given appid will only ever appear within
|
||
* the highest-precedence directory that contains it. We never
|
||
* return search results from a lower-level directory if a desktop
|
||
* file exists in a higher-level one.
|
||
*
|
||
* - within a given directory, the string is unique because it's the
|
||
* key in the hashtable of all app_ids for that directory.

||
*
