Search-engine on docs.altinn.studio has unexpected results

### Description of the bug

When searching for a very specific term/word on docs.altinn.studio, it presented a long list of unwanted "hits" from small parts of the word I was looking for. The "exact hit" was far down the list of the searches.

Today (19/9-2025) it has suddenly changed its behaviour, because now I get NO hits for the same word.

When I search for only "SSB" I can see that there is documentation for the phrase I was looking for.

If I search for **"services.AddSSBClassificationCodelistProvider"** instead of **"AddSSBClassificationCodelistProvider"** it actually finds it right away. It seems like it is trying to find the **beginning** of the word first, in this case the "word" seems to start with "services". I tested searching for **"ategorisering",** and again it doesn't really find the word **"kategorisering"**, it mainly returns words starting with "at" like this:

### Steps To Reproduce

1. Search for AddSSBClassificationCodelistProvider on docs.altinn.studio
or any other part of a word (except the beginning)

### Additional Information

See discussion on Slack: https://digdir-samarbeid.slack.com/archives/C02EJ9HKQA3/p1757667323727839

Start by reproducing the searches on docs.altinn.studio for "AddSSBClassificationCodelistProvider", "services.AddSSBClassificationCodelistProvider", and "ategorisering". Trace the documentation site's search entry point and identify the matching behavior; done means relevant exact or partial-word matches appear prominently without the reported unrelated results.
