Rewrite URL of search query page through htaccess

Hi, ON my website I have a search page where filters works with ajax. and it generates URL with every input in format : [login to view URL] ..... and so on.. i want you to change it in : [login to view URL] ... and so on.... (remove "page1/page2" , replace " &var= " with " / " and remove "-valueID" ) in a way that my search also works fine with that. For real e..g : if i select category it shows a URL: [login to view URL] change it to : [login to view URL] after that if i select a sub-category then URL : [login to view URL] change it to : [login to view URL] /subcata after that if i select a filter of location says new delhi, delhi, india the it shows URL : [login to view URL] change it to : [login to view URL] or any better version for location if you suggest. and so on for more filters like gender age etc. *NOTE : You only need to write .htaccess rules for it . If any internal coding needed then you can ask our developer to do that. I hope its a small task for the person who knows .htacess well. I am quoting price according to that, if you think it's critical task and should be paid more then you can ask for more money but you need to explain the criticality a bit.
