Search cannot find non-alphanumeric symbols

[mabdullahsoyturk]

Non-alphanumeric symbols do not seem to be appear in search results. For example, if one searches for "<" or "$" symbol in GAMSPy docs (which uses pydata-sphinx-theme), there seems to be no matches even though there are matches (see $, and <). Is there a plan to include them in the search results? If not, can you point me which script to look at for potential changes?
