Add a search results branch for automating QA

[agjohnson]

We should have a branch and some test suite available for this branch in order to help test search query hit/miss rates. There are a number of ES features we might want to test here as part of our production QA tests:

• Word stemming mismatch -- ie docs have "eating", query is for irregular "ate". Same for regular stem mismatch -- "cooking" vs "cooked"
• Case mismatch -- ie docs have "PizzaPie", query is for "pizzapie" or "PIZZAPIE" etc
• Compound mismatch -- ie docs have "Calzone", query is for "cal zone". Opposite as well.
• Punctuation mismatch
