summary

Shows a concrete system that replaces a single concatenated Solr fuzzy index with a pre-query matrix that tests each input token against specific fields, implemented as a Scala Solr request handler and AJAX front end. Uses production logs, runs ~50–100 tiny field-queries per request over ~10 million address/POI points, achieves typeahead within 40 ms latency, and improves precision by preferring matches where tokens map to city/street/house-number fields. Calls this technique field inspection and reports clear production improvement.
