Incorrect search result for some texts

Question

Hello,

I'm writing about search issue in JIRA 6.1.

When I'm starting to search for issue with examples criteria below,

1. issuetype = "ABC" AND text ~ "QC5F"

2. issuetype = "ABC" AND text ~ "Treethawat"

Regarding the first search, I got 3 issues as result.

But for the second search, I got 5 issues as result.

Those issues contained a string as "Treethawat/QC5F" or "Treethawat / QC5F" in a description or some fields.

I have no idea why the first query doesn't show 5 issues the same as the second query?

Thanks

Hi Boris,

Thanks for your quick response.

But if I search as follows:

* issuetype = "ABC" AND text ~ "QCCF" : Result is correct
* issuetype = "ABC" AND text ~ "ABCF" : Result is correct
* issuetype = "ABC" AND text ~ "QC3F" : Result is incorrect
* issuetype = "ABC" AND text ~ "AB4F" : Result is incorrect

There might be something wrong with digit rather than string while doing search.

This might be due to the "word stemming" which is used by the JIRA search. See this for details - https://confluence.atlassian.com/display/JIRA/Performing+Text+Searches#PerformingTextSearches-Wordstemming
