Hi,
This might be a very silly question that's documented everywhere but I
just can't find an answer right now.
When we first implemented solr we used version 1.2 (of course, 1.3 was
released days afterwards). In the brief period we used 1.2, whenever
we wanted to delete a bunch of documents, we would send along
something like this:
<delete><id>image.1</id></delete><delete><id>image.2</id></delete>
etc... (one delete node for each image we wanted to delete)
And that worked in 1.2.
Also, we could get a statistic called "deletesPending" from the
stats.jsp page in the admin console.
Now, when we upgraded to 1.3, I noticed right away that deletesPending
was gone, but since it wasn't critical to the application we kinda let
it go. Now, first of all, I'm wondering, is there any way to get this
statistic back? I've checked the document because I know precisely
how many deletes should be pending right now (135 documents), and that
statistic doesn't appear to be on the page at all by any name, any
more. It was very useful though! If there's any way to poll the
index for this information still, that would be great.
Also, and this is the part that really gets me, somehow now that
delete command that we were using no longer works. I can't find any
reference to the fact that it changed anywhere... But I know it did
because I have the logs from when we tested it (just went back to
check).
Now I rewrote our scripts to do a delete by query like this:
<delete><query>id:(image.1 OR image.2)</query></delete>
And that's fine. Just wondering if that was actually a change or
what's going on there or if the fact that it ever worked was a fluke
(which seems to be the case since I find people out on message boards
essentially saying the delete by query method is the only way to
delete multiple documents at once). I'm kinda worried that syntax for
other commands might have changed without my knowledge (but only a
little - after all, it took about 4 months before someone noticed
deletes didn't work properly - it's not the most common thing for us,
but still, that's a long time).
If anyone knows the answer to these questions (in particular, the
deletesPending statistic) I'd really appreciate the hint. Thanks!!
