Intelligent autocomplete for text search

[AntonPetrov]

Background

To make it easier for users to perform precise searches without knowing Lucene syntax or selecting facets, we can implement autocomplete by category similar to how it is done in PDBe:

This should work well for simple searches like human or mir-100. For more complex queries, we need to parse queries and perform more advanced processing which is a separate issue.

Implementation

• [ ] create a new Solr index
• [ ] index a subset of data (Organisms, Genes, maybe Authors)
• [ ] update the UI to show autocomplete suggestions
