edms: query relevance debugging

Some queries do not produce the expected results:

EDMS dev

?access=en-dep-ace-plm@cern.ch&q=NOT-0010+AND+_data.object_type:D+AND+_data.obsolete:false&size=100

Returns the firsts results just with NOT in the title (e.g. 59355). However, records such as 142684 containing NOT-0010 appear much later in the results (having to set up size=100 to see it).

?access=en-dep-ace-plm@cern.ch&q=(_data.author.full_name:(nikitas.kotsolakos@cern.ch)+OR+_data.author.email:(nikitas.kotsolakos@cern.ch))+AND+_data.object_type:D+AND+_data.obsolete:false&page=1&size=100

First returns results with no match, then the revers kotsolakos.nikitas@cern.ch and only later on some with the queried email.
