Include signatures in search results

[chasenlehara]

As a user, I’d like to search for canViewModel and get https://canjs.com/doc/can-view-model.html as a result.

This could be accomplished right now by indexing API signatures.

Here’s what I think needs to be done:

• Modify https://github.com/bit-docs/bit-docs-generate-searchmap/blob/master/generators/search-map.js to include API signatures in the searchObj (I’m assuming the docMap already has these signatures)
• Check the size of the search map that’s generated. If it’s a huge increase, we might want to just index the first part of the signature, e.g. canViewModel(element) -> canViewModel [we might want to do this anyway?]
• Add the field to the search indexer

  indexData: function(items) {

• …?

For now, I don’t think we need to show signatures as search results, just show the page as a result when you search for a signature it contains. It might be a nice improvement in the future to show the signature as a result and link directly to it.
