Add ability to search by string

The current elasticsearch is fundamentally a keyword search function.

Searching for "black pipe" will returns results with "black" or "pipe" in the data set.

Our executives feel that the search results should only include those items with "black pipe"; and not other instances where "black" is not followed by "pipe".

I fully appreciate the need to be able to treat searches as a keyword search.

However, I'd also think that there would be a way to limit search results to those where "black pipe" including the space are located exactly in that order.

As a point of reference I recall an internet search engine that permitted the use of regular expressions (definitely an advanced search technique), and the use of "." (period) to represent a wildcard or space.
