Bridge search is not exact

[svenrdz]

I think the facets do not work properly for the bridge. For example, using index_node = "esgf-node.ornl.gov/esgf-1-5-bridge", the query

esgpull search experiment_id:amip-hist variable_id:tas frequency:mon source_id:MPI-ESM1-2-HR variant_label:r1i1p1f1

returns

Found 108 datasets.

Even though I only request experiment_id:amip-hist, it returns also other experiments that include amip or hist separately.

This search query seem to narrow it down to only the given value for experiment_id (note there are 2 kinds of quotes ' and "):

esgpull search experiment_id:'"amip-hist"' variable_id:tas frequency:mon source_id:MPI-ESM1-2-HR variant_label:r1i1p1f1

Fix: We should force quote all search terms for the bridge API in the code.
