Inconsistent number of search results when searching

Hello,

I have a strange bug. When I search something with Ivory Search, I get directed to the search results page with inconsistent search results. Some examples:

“1 Search result for test”
“Unfortunately nothing found” // One result not shown

“4 Search results for quality”
3 items are shown, with five incidences of “quality” highlighted // One result not shown

“0 Search results for asdfasdfasdf” // As expected
“Unfortunately nothing found”

If take a search term, where I know it exists at least once on the page (a rare word like perpendicular), I will get
“1 Search result for perpendicular”
“Unfortunately nothing found” // One result not shown

It seems like Ivory Search is withholding exactly one search result from the result page. I have looked in the settings, but was not able to find anything that seems to change this behaviour. I could use some advice for this.

Thank you.
