search - autocomplete: autocomplete caches interferes with display od properties and attributes

[danilos]

when performing a metadata search, the auto complete feature of the search field interferes with the display of the list of properties available to the user in defining a search criteria

another issue with the cache is that a user cannot perform a new search using the same text string typed even though the criteria for the search might have changes. e.i. changing between simple to metadata search does not allow a user to perform a new search
