Avoid error in search when the parameter received by IndexQuery is a …

…record (#130)

When using record notation in URL parameters, for example:

http://localhost:8080/Plone/@@search?end.query:record:list:date=2022-2-2+00%3A00%3A00&end.range:record=min

On the Zope side, this parameter becomes a
ZPublisher.HTTPRequest.record, not a dictionary.

However, IndexQuery only expected the parameter to be a dictionary. When
the parameter is a record and it is not considered when extracting the
'query' key, the error occurs:

TypeError: unailshable type: 'record'

in search.

Now we consider that the parameter can be a record as well.
