Description David Gibson 2017-12-13 02:59:07 UTC 
Description of problem:

Searching documents is weirdly unreliable as of quite recently.  There are several symptoms:
    * Sometimes it reports "0 found on this page" even with one highlighted on this page
    * Often "Find Next"/"Find Previous" don't find anything even though there are known other matches in the documents
    * Sometimes rapidly, repeatedly clicking the next/prev buttons will cause it to find matches it didn't with a single click.

Version-Release number of selected component (if applicable):

atril-1.19.5-1.fc27.x86_64

This problem has appeared quite recently, but I don't know exactly what package version it started at.

How reproducible:

At least on certain documents seems to happen most of the time.

Steps to Reproduce:
1. Open large PDF document with some know search terms
2. Press Ctrl-F
3. Type a string know to appear repeatedly in the document
4. Press "Find Next" to step through occurrences of the string

Actual results:

Generally finds a first match correctly.

May print "0 found on this page" even with a match highlighted.

Find Next/Find Previous may not find additional matches even when they exist.

Expected results:

Find Next/Find Previous reliably step through matches in the document.

Additional info:

Find Previous seems to be slightly more reliable than Find Next, but it's hard to be sure.

An example document which demonstrates this problem can be downloaded from:

https://openpowerfoundation.org/?resource_lib=ibm-power-isa-version-2-07-b

Search, for example, for "hfscr" in this document and the weird behaviour described above shows up.
Comment 2 Wolfgang Ulbrich 2017-12-19 08:28:40 UTC 
Was this a problem with atril-1.18.1 from f26/f25 ?
Comment 3 Wolfgang Ulbrich 2017-12-19 09:13:36 UTC 
Confirmed, but it seems that the problem occurs only in continuous mode.
Also, it doesn't matter if single or double page is chosen.
Do we have a cache problem?
Tested with your PowerISA_V2.07B.pdf document.
Good that it isn't a problem with the new feature caret-navigation.
Comment 4 David Gibson 2017-12-20 02:44:32 UTC 
I'm pretty sure it wasn't a problem in f26 or f25 - I certainly didn't notice it until recently.  I didn't notice it until after the fix for bug 1513826 went in.

Thanks for pointing out it only reproduces in continuous mode, I hadn't noticed that.  That gives me a workaround which will make life much less painful.

Can you please test https://koji.fedoraproject.org/koji/taskinfo?taskID=23972942
This fixes the regression for me.
Hope i don't introduce another one.
