I forgot to mention that there are a total of 180 records (and therefore 180 items, we don't have many dups) with the Copy Location of HPL Display - Read 15 in '16, and therefore only 180 records in the Copy Location Group. So the issue is happening even with a tiny search query.
Thanks for sharing, Kathy. I have been seeing this issue for a while (as with our New Books location), but haven't had the time to really dive in yet. I'm ready now! -Holly From: Open-ils-general [mailto:[email protected]] On Behalf Of Kathy Lussier Sent: Thursday, January 28, 2016 1:47 PM To: [email protected] Subject: Re: [OPEN-ILS-GENERAL] search results mystery Hi Holly, I'm a bit fuzzy on the details for this, but we ran across a similar situation a few months ago when using copy location limiters. There is a very brief IRC discussion this issue at http://irc.evergreen-ils.org/evergreen/2015-10-21#i_210396 . I meant to file a bug report, but I never got around it. Basically, the estimated results count starts to get inaccurate once you hit something like 1,000 results (this is configured locally and could be different on your system.) The copy location limiters are applied after the core search, so, even though the final count is way below that number, your core search without the limiters actually exceeded that number. I'm guessing the same happens with copy location groups. I'm sure somebody else here could explain better than I just did, but I just wanted to let you know that we've seen this issue too.

For my single-branch library , the Library filter is just different Copy Location Groups. I can't find my specific issue on Launchpad, but I'm also not really sure what's going on. This issue happens with all my Copy Location Groups, but here's what happens with a specific, basic example: I have a Copy Location Group consisting of just a single copy location, HPL Display - Read 15 in '16, in the Location Group named Read 15 in '16: [cid:[email protected]] When I search using only this "Library" filter, like this... [cid:[email protected]] I get these results on page 1, with about 210 results: [cid:[email protected]] Jumping to Page 8 of results, and suddenly I have about 115 results: [cid:[email protected]] Jumping to Page 10 of results, I have about 92 results: [cid:[email protected]] The results are "consistent" in that if I return to page 1 (or any other page), the number of results is the same as the first time I viewed that particular page (Page 1 always says 210, Page 8 always says 115). BUT THEN, an hour later if I search again, the first page says 270 results... consistently. So my question, I guess, is "What's the deal?!" Is the interpretation of "about" in the number of search results really THAT elusive? Help please, and thank you. -Holly Holly Brennan Library Technology Specialist Homer Public Library, Alaska [email protected]<mailto:[email protected]> 907-235-3180 (main) 907-435-3154 (direct) -- Kathy Lussier Project Coordinator Massachusetts Library Network Cooperative (508) 343-0128 [email protected]<mailto:[email protected]> Twitter: http://www.twitter.com/kmlussier
