Thank you very much for answering so fast. Unfortunately it didn't did what i was hoping for.
I don't know if i explain you more if you could find the answer (i can only do some simple edit, not build codes you know as i'm not a developper)
I'll make a first donation if you can solve my problems and a bigger one once my site is launched and i get my first income from it (that would be normal if, thanks to you, i can finalize my website and get income from it, to reward you a bit more for your help).
I explain the problem.
I'm using jobroller theme (from appthemes), a job board theme.
The theme has no advanced search system to search by sidebar, multi selection etc. just a very basic search (if we can even call that a search widget) as you can see on their demo page http://demos.appthemes.com/?theme=jobroller
So i bought a plugin especially made for that this theme but, i've been mislead by the author as he made me believe his widget will do multi selection and multi option search. Results: it was a lie, it doesn't work well on job_listing search (no multi criteria search like he claimed) and don't do at all multi select. So i spent 29$ for nothing.
Then i bought an advanced search plugin on another website, it worked, but i didn't realize before i buy that it won't do multi form, so it was useless for me. I spent 19$ for nothing.
2 days ago, i found on codecanyon a plguin that will do multi form, so i bought it thinking my problems wil lfinally be sovled. It worked for job_listing but not for resumes, so 19$ for nothing.
Then i found your plugin that does everything i needed. The worst is that i've searched on free plugins before buying plugins, and didn't find anything grrrr.
My problem is hard for me, but might be simple for a developer like you.
As i explained you there are 2 post types on jborolelr theme
On the theme there are specific sidebars, so i add the widget this way:
1.custom form i created for searching job listing on main sidebar (it displays on homepage) and single job listing sidebar.
For this part, it works flawlessly after i made some edit in theme thanks to the help of the author one of the plugin i bought, it seems to do the trick for any custom search plugin working with this theme)
2. custom form i created for searching resumes on resumes sidebar.
And that's where i have problems.
When i make a search, it returns results BUT 3 problems happen:
a. The display look is not the same as it is with default basic search from theme (or as it was with the search especially made for this theme). It displays in black on not in color and is not "arranged" the same way.

b. when i click on search, i get search results (but not displayed correctly as shown on image above) BUT the resume sidebar is purely replaced by main sidebar, it's very weird (but when i select a resume to visualize it, the sidebar is the good one (resume sidebar) touhgh, even if when'ill make a new search it will be replaced with main sidebar again (so the one for job listing search).
That's why i thought that including a condition like the one you gave me will resolve the problem.
c. the resumes search, even if the search resume sidebar is displayed should be avaiable only to does who have subscribed. But with a custom widget not especially made for the theme, contrary to what i thought at first, it doesn't take into account the fact that search resume shouldn't be accessisble if there's no subscription/paid pack active you know? So anybody can do the search and get results instead of getting the message "blabla you need to subscribe" once you click on search.
I think that all the elements/terms can be solved at the same time with conditional stuffs that are in on file of the theme called "resume-search.php" even if it's made for very basic search, but i'm not a developper so i'm so lost :(
http://pastebin.com/NuMMLHPT > search-resume.php code
http://pastebin.com/feZvmExG > search.php code (just in case)
In both files, there are lot of useless code as far as i don't use the basic search etc. it's just for pieces of code to make your plugin stop doing the 3 stuffs i mentioned in resume section :)
I'll greatly appreciate your help :)
