Hi,
I've been reading the mw.org and wikitech pages on Cirrussearch (and the code) in the hope that I will be able to understand how is the page content transformed before being sent to ES and how is it kept in ES and I have a few questions:
1. Is the documentation available anywhere? I don't see it on https://doc.wikimedia.org/
2. What part of the whole ecosystem transforms the wikitext into indexable text? Where can I find it? It should be somewhere downstream fromCirrusSearch\Updater::updateFromTitle(), but I can't figure uout where exactly.
If this transformation doesn't happen, from where is the searchable text obtained?
3. Where can I find the ES schema used for wikipages? Is it different for images/categories?
Thanks, Strainu
