suggestion: incorporate SEARCH code from GPL "findwild" util

[stewie]

Toward enhancing spaceFM search functionality without "reinventing the wheel",
consider incorporating the underlying code (if not its GUI) of kornelix "findwild" utility.

Although findwild lacks a cli interface (and, I believe, requires libgtk 2.64 minimum)
most of its functionality stems from "zfuncs" package

findwild
This is (yet another) program to search for files, but it works differently.
Findwild offers the following search criteria:
* directory path to search, with multiple wildcards placed anywhere
* file name(s) to search for, with multiple wildcards anywhere
* file name(s) to exclude, with multiple wildcards anywhere
* file content string(s) to search for, with multiple wildcards anywhere
* file content string(s) to exclude, with multiple wildcards anywhere
* file modification date within a desired range
* delimiters for the strings to be searched (defaults provided)
The search criteria can be tuned to narrow the search by excluding unwanted paths / files / strings included in an initial search.
Combinations of wanted and unwanted strings can be specified at the file and record level.
Search the results of a prior search with new criteria (narrow the search, stepwise, with fast response).
(IOW: "search within results" ~~ A new search can be initiated using the results from a prior search to speed things up.)

Search criteria can be saved in a file and recalled to edit and use again.
