searching "barrier" at the website should find picket_fence etc.

In this case: maybe search at https://pinhead.ink/ should also search in folder names?

In this case it is in https://github.com/waysidemapping/pinhead/blob/v15.23.0/icons/barriers/fence.svg so using also barriers as searchable would fix this problem for barriers in general

and if "Filter pinheads" is not intended to support any synonyms etc. - maybe "Filter pinheads by icon code" would be more clear to indicate it is not smart and not intended to be smart?

Currently Pinhead gets search terms from Wikidata. We could expand this to match the OSM tag and OSM key Wikidata properties, so searching "barrier" would match things like barrier=fence. Searching by folder name also sounds okay.

In the meantime, I've added Q264661 as a possible "symbolizes" at https://commons.wikimedia.org/wiki/File:Fence_Pinhead_icon.svg and a couple other icons, which should add obstacle, barrier, impediment (and equivalents in other languages) to the search terms for it once the web site indexer picks it up.
