JQL Documentation needs clarification on the exact phrase "full screen" sample for advanced text search

Our documentation at https://confluence.atlassian.com/jirasoftwareserver/advanced-searching-operators-reference-939938745.html states:

Find all issues where the Summary contains the exact phrase "full screen" (see Search syntax for text fields for details on how to escape quote-marks and other special characters):

summary ~ "\"full screen\""

That creates the expectation that we can do an exact search on Text fields, while Lucene will return similar matches due to the stemming process.
Thus, when users do a search like

"Projeto Gitlab"  ~ "\" wkl_ek4_api_cartoes \""

It will also returns:
wkl_ek4_api_cartoes
test_wkl_ek4_api_cartoes
wkl_ek4_api_cartoes_test
