"ISM" causing a wildcard affect when text searching

[Michael Goldberg]

When I perform a text search in jira for the word "ageism" it returns results that include the word "age" in their description and/or summary.

When I perform this same search with something like "ageish" it does not return the results that have "age" in their description and/or summary.

What makes ISM at the end of word act like a wildcard or "*"?

Are there other three letter combos that act like a wildcard or "*"?

How do you turn it off? (Putting the search word in quotes has no affect.)

Hi @Michael Goldberg 

What you describe seems to be an overlap between the "fuzzy" and "prefix and suffix" searches with the JQL CONTAINS ~ operator: https://confluence.atlassian.com/jirasoftwareserver/search-syntax-for-text-fields-939938747.html#Searchsyntaxfortextfields-fuzzyFuzzysearches:~

I have not found specific documentation on the terms used for JQL fuzzy search versus when prefix / suffix applies.  Guessing a bit, perhaps because "ism" is less colloquial than "ish" suffixes it is included in the fuzzy-parsing.

Kind regards,
Bill

@Bill Sheboy Thank you for the reply.  The link you provided led me to this section about stemming:

• Your Jira administrator can disable word stemming (so that Jira will find issues based on exact matches with words) by changing the Indexing Language to Other (under Administration > System > General Configuration).
• Word stemming applies to all Jira fields (as well as text fields).
• When Jira indexes its fields, any words that are 'stemmed' are stored in Jira's search index in root form only.

Unfortunately changing this setting did not fix the issue.
