Searching issues based on specific string fragment in summary

[AnupamS]

We have a specific requirement where we want to search issues based on specific summary fragment.  

I went through the link to get a grasp of the rules in Jira search.

https://confluence.atlassian.com/jiracoreserver073/search-syntax-for-text-fields-861257223.html#Searchsyntaxfortextfields-stemming

The issue is that the summary for our issues is not verbose, rather it is combination of many not-so-English strings with length in order of 50-100 characters, and we want to search based on some keywords which maybe clubbed in between the entire length. These snippets are not English words/stems which can scale up for the search. Our stemming is set to moderate which is default I guess, but given the requirement so specific, I am not sure if varying this will help.

Is there any other way from configuration/other means that can help us achieve this?

Looking forward to wisdom from across.

Hi Anupam,

What does your search like right now? Can you post an example?

[AnupamS]

Hi John, thank you!

My search criteria is something like

summary ~ "psf"

summary ~ "psf*"

Here, I want the summary to contain the fragment "psf" 

The results with of the first query has issues with summary (replaced the key words with dummy values).

String A| String B | String E par_psf_pcie
String A| String B | String E par_psf_pcie
String A| String C | String E par_psf_pcie
String A| String B | String E par_psf_pcie
String A| String D | String E par_psf_pcie
String A| String D | String E par_psf_pcie
String A| String D | String E par_psf_pcie par_gmm par_lgcio_pch par_disp

results with second query are (with *)

String A| String B| String F par_psf_pcie
String A| String B| String F par_psf_pcie
String C | String G par_tme, par_psf1, par_psftctop, par_usbx_usb3_com, par_sa_misc, par_tbt_ports, par_psf4, par_lgcio_misc, ddrrptchtop, par_iunit, par_fmhc, par_fivr_core_right, par_fivr_core_left, par_mee
String A| String B| String F par_psftctop
String A| String D| String F par_psf_pcie
String A| String B| String F par_psf_pcie
String A| String D | String F par)psftc4
String A| String D | String F par_psftctop
String A| String E | String G par_psftctop, par_psf4, par_lgcio_misc, par_psf1, par_tme
String A| String D | String F par_psf_pcie par_gmm par_lgcio_pch par_disp
String A| String D | String F par_psf_pcie
String A| String D | String F par_psf_pcie
String A| String E | par_dmi_tl, par_disp, par_pcie4, par_psf3 andpar_psftctop

The issue is that we still have more issues which have "psf" such as 

String A | String B| String C: par_psf4

or

String A | String B| String C: par_psf0 (and many more)

These don't show up in the search.

Maybe try summary ~ "psf~"

[AnupamS]

HI John,

This is giving issues which doesn't have "psf" as well (psf-like issues?)

few results:

String1 | String2_nsf_top | String 3 --- nsf is psfish...

String1 | PSG_String2 | String 3---(PSG is psfish..)

[John Funk]

:-(   

Maybe try  summary ~ "_psf~"

[AnupamS]

Nope, doesn't work :(
