Use proper eZ Find fetches in default admin2 and standard search templates

[peterkeung]

Previously, sorting was broken because eZ Find sorting uses different syntax. Regardless, eZ Find search templates should be using eZ Find fetch functions.

Agreed and +1.

What do you guys think @dpobel @bdunogier @lolautruche @andrerom @paulborgermans @patrickallaert @crevillo @masev ?

Thanks and keep-up Peter!

[paulborgermans]

Fine for me, although I am wondering if the search should return results sorted by the (ezfind default) relevancy instead of modification date?

[nfrp]

+1 for relevancy here, indeed.

[peterkeung]

Yes, although for the 2 clients from which this pull request came from, it was very important for them that the default behavior in the Administration Interface was to sort by modified date. Maybe for the front-end we can have it sort by relevance but keep it as modified in the Administration Interface?

[nfrp]

Ok here to simply introduce the change in fetch function signature, and keep the sort order as was.
The relevancy ranking can be introduced separately indeed.

[harmstyler]

+1 for merging this commit as is and deciding upon switching to relevancy as the default separately.

[nfrp]

Merged, thanks!

PS @peterkeung, @harmstyler or @paulborgermans : feel free to introduce the relevancy-based sorting for the front-end, in a separate PR.

Cheers,
