[Wikitech-l] Advice on Tuning Search?

Can anyone point me to a starting point for learning about how to tune CirrusSearch (or examples)? I found the CirrusSearchScoreBuilder page [1], which implies it is possible to modify how search results are ranked. But, the documentation page hasn't been created yet. Thank you! [1]:

What if I don’t own the copyright to my photo ? The current format of the LICENSE file allows me to specify a different license, but not who the image should be attributed to. Am Di., 9. Okt. 2018 um 12:52 Uhr
