Hi rhys, You are actually looking for an autocomplete! I work for the Auto-Suggest (different names for the same thing) team at Indiamart.
Although we have a long journey making our Auto-Suggest one of the fastest on the internet, I hope this summary will help you. You can always connect with me for any doubt. 1. If you don't have a high number of documents, you can use wildcards in the query for a simpler implementation. That means, you just convert your query from q=app to q=app* so that it matches "apple". Wildcards have its own cons (constant scoring, high QTime) and since it's a multi-term expansion, you cannot use many analyzers over the query. It had been performing well (under 50 ms QTime) till we had 22 million documents (which is still a large number of documents). 2. Now that we have over 60 million documents, we have shifted to Edge NGrams <https://lucene.apache.org/solr/guide/8_3/tokenizers.html#edge-n-gram-tokenizer> on the index side. Using this, your highlighting should work as expected and as you do in normal searching. 3. You also have Suggester <https://lucene.apache.org/solr/guide/8_3/suggester.html> component for Solr that you can use for basic suggester functionalities. Supports highlighting. >From my experience, the best solution is Edge NGrams (2). We have over 60 million documents and still a 25 ms QTime and we do complex scoring and analysis.
