Website magazine search improvements
I have made some minor improvements to the search function today.
Searching a specific publication for an article or topic would usually take a very long time and often return an error page. I have improved this so it is now much quicker and there shouldn't be any errors.
I've also added the ability to search by year range: either a minimum year or maximum year or both. The only issue with this is that magazines without a year (eg. magazines that are undated) will be excluded from searches with a year range.
