Second, Wikimedia still hasn't aggregated and released anonymized search data. People use Special:Search daily and they encounter a page of search results instead of having a redirect take them to the appropriate destination. Or sometimes worse there's no coverage at all of what our users are searching for. It's a long tail, yes, but we could start filling in gaps if we had data about what users are looking for. We could save users a lot of time and build better sites by analyzing what users are looking for and not finding or what they're looking for and not immediately being redirected toward. And yes, of course, there are privacy considerations (the infamous AOL case, c.), but nothing insurmountable.

That would make it easier to find out whether the search fails because the query is parsed differently from what you imagined, or because there really is nothing to return. You can _kindof_ get that now by adding the cirrusDumpQuery url parameter. But it only dumps the query as sent by Cirrus to Elasticsearch and that contains a query_string query that Elasticsearch (Lucene really) parses on its own. One interesting option would be to make a way for Cirrus to return Elasticsearch's explain results. Its not perfect because it only explains why things are found and scored the way they are but it doesn't explain why things aren't found. Exporting the actual parsed query is more ambitious.

Its pretty much the same as a regular search but limited to the title field. incategory:Foo OR intitle:Bar is a limitation I'm working on now. No idea when it'll be avilable. Limitation comes from us trying to be cute with the command parsing in Cirrus and not writing a whole grammar for the query language. Regexes only work for wikitext. This is a somewhat arbitrary decision on my part - we need to made special ngram fields to accelerate the regex searching and we only do that for wikitext. We _can_ do it for other fields at the cost of update time and disk space. Nik ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

To really make this awesome we need structured data support for Commons with Wikidata. We'll be making more progress on it in the second half of this year but there is a lot to do. Sure, to really make that awsome, yeah you need wikidata. But we are far away from hitting the point where we need wikidata. In fact the three examples McBride gave don't need wikidata. mime type and file size are easily programmaticly available already. And unless I'm mistaken, functionally dependent metadata like algortihmically determined main image colour, are out of scope of wikidata. --bawolff ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

We've been thinking about this a bit but no decision has been made. It'd be nice to make these accessible in the same way as other properties without needing to store and maintain them the same way. We've been thinking about some kind of fake properties for example. But we'll worry about that when we get there. We're getting a bit off-topic. Sorry, Dan.

It shouldn't be WMF specific (since its not WMF specific like TOS links), it should be specific to CirrusSearch. One possible implementation would be to do an override message (I would note, that the wikimediaoverride messages aren't direct overrides, they are replacement messages used by other code that does the overriding). In my original email I was thinking more from a user perspective of what I'd like to see, without thought to how it would be implemented. Without looking at the code, I would probably favour an extra hook just for the search module, instead of using the generic hook.

Especially if all the parameters were documented in the normal api way, I think it would represent a big boon to discovering the hidden features of search.
