When you attempt to search for issues in JIRA with special characters ( - ) some issues are returned, however, not all issues are returned.

How to Replicate:

Create 5 issues:

test-test
test-1test
test-1test-1
test-25-test-2
test-322-test-4

Search for Search for summary ~ "test"

The results come back and the only issue that is found is test-test

The first issue is returned but the rest are not.

Attempting to escape the characters with \ or
per Search syntax for text fields does not work.

A search for summary ~ "test*" returns the issues but also returns more results than the intended data set.
