Bug 22595: Items search is mixing inputs

Items search is using inputs and selects from search form to create an Ajax call.

In this call selects are parsed before inputs.
But a custom search field can be used with authorised values and used after a regular search field.
In this case the "q" param is not ordered like the "name" param.

Test plan :
1) Go to Administration > Item search fields
2) Define a search field with an authorised values category
3) Go to items search
4) Use a regular filter like call number
5) Click on new field
6) Use custom field with an authorised value
7) Perform search
=> Without patch you get wrong resuts, authorised value is used as value for first field
=> You can see this by listening traffic in Firebug, look at params "f" and "q"
8) Check some combinaison of select and input filters
