Search does not find parts of words

[Danke23]

Describe the Bug

If I search for “onboard”, the search finds the word “onboard” - if I search for ‘board’ or “boarding”, the search no longer finds anything.

Steps to Reproduce

1. Create a Page with "Onboarding" Text or Title
2. Search for "boarding"

Expected Behaviour

I would like the search to find boarding in the word onboarding.

I've been seeing this problem for a while, so confirmed over here.

Yes please fix this, and also need to add feature where tag doesnt disappear after saving page draft

This is known and intended. Search for standard terms is performed via a prefix match against indexed search terms (to make use of database indexes). A exact search term ("in quotes") will perform a slower exact match across the whole range of content text.

@ssddanbrown Okay, that makes sense. thank you.

[Danke23]

Okay, thank you very much for your answer. That's how it works.
However, this is somewhat impractical. I think it would make more sense to make this search for “exact search” the default search.

The naming is also confusing: For me, an exact search is the exact word and a normal search is a word snippet too.

I think it would make more sense to make this search for “exact search” the default search.

The reason we do a prefix-match by default is because then we can actually use database indexes, and therefore search remains fairly performant, otherwise the exact search (or inner partial match) does not use indexes which can be quite intensive since it requires a full scan/search across content, and this scales linearly with content size, so is something I'd want to make default.
