Today, I tried to use the TeX & LaTeX search bar to find examples of code that use the macro text_expand (a macro from the l3text module)
The following lists what I tried searching.
text_expand(link)"text_expand"(link)\text_expand(link)"\text_expand"(link)code:\text_expand(link)code:"\text_expand"(link)
In all those searches, I got the following message:
We couldn't find anything for <<my input>>
Search options: <<options for my input>>
Try different or less specific keywords.
However, when I tried searching site:tex.stackexchange.com "text_expand" in DuckDuckGo (link), I found three results (see screenshot below.)
Why doesn't the search bar list those answers that are found by DuckDuckGo?
