Adapt code in Keyword Search to use location field text also

To adapt the current Keyword search section on the left hand side of the site [login to view URL] to be inclusive of also the Location field text so it pulls things written as a location keyword. This has been done once before and worked fine but has to revert due to other current work and testing. we would like to add this back in and is not a big job at all. You can see if you search by keyword and enter the location "chester" see here [login to view URL] it will only show one event. this is due to the word chester being in the Title. But actually has more listings as you will see here [login to view URL] We would simply like to add the locations fields within the search to the left. There is a code page of strings that can be changed to include these fields somewhere within the site. This should change the way [login to view URL] searches also but if not strings would also have to be placed in this site the same once found.
