[16.15] Unusual Search Results

[Malachite]

When playing along and searching in the crafting menu (via ctrl-f) for some basic resources, i found some unusual results.
- A search for "coal" gave me the fill and empty oil barrel recipes and copper cable
- A search for "iron" gave me some usual suspects, but also basic oil processing
- a search for "copper" was as expected.
- a search for "circuits" was as expected.
- A search for "stone" returned the usual suspects but also fast underground belts.
- A search for "belts" returned the usual suspects but also Big electric poles.
Removing all mods had no change.

I suspect it looks like its checking for the letters in the word in the correct order, I.E.
BELT -B-ig -EL-ec-T-ric pole
STONE fa-ST- undergr-O-u-N-d b-E-lt
COAL fill -C-rude -O-il b-A-rre-L-

It's not a bug. Works as intended. And you guessed right, the search engine searches the letters in this order anywhere in the text, not nécessarily contiguous.
