[eclipse-pmc] Request to backport performance improvement for Text Searc

[Mickael Istria <mistria@xxxxxxxxxx>]

Hi all,

I'd like to request PMC approval to backport change https://git.eclipse.org/r/#/c/75921/ to 4.6.1. In the case of complex modular projects (typically Maven ones) it results in a sensible performance gain when doing a text search (move from 14s to 10s on my example).
The change is not trivial, the text search is a critical feature and the existing tests are not really strong since they don't cover the text search very well. Sergey already helped in reviewing it and the change got part of 4.7.M1. I also successfully ran a bunch of manual tests on big projects to check that this change didn't impact the search result and actually resulted in a worthy performance gain. So despite the risk of including such a change, I believe the various reviews and manual tests validate this change.

Is PMC fine with shipping this performance improvement as part of 4.6.1 ?

Cheers,
