Dears, We run a search engine for second hand products. We have about 500 million ads in the database which runs on Apache Solr 6 with 2 shards. These ads highly rotate every month, which cause a lot of update and select (about 50 / seconds). We have some performance issues. We would like to update the data in less than 200ms and select the data in less than 100ms. We have specific filtering/faceting such as : sorting, filtering, geolocation but also paging. We need expertize of an Apache Solr consultant to improve the performances and stabilize the activity. If the collaboration goes well, we have more projects : relevancy improvement, deduplication, etc.

Project is at the idea stage and i'm discussing it with potential partner but to go forward i would need to have some numbers on possible expenses. Can you estimate how many hours it may take to develop solr or lucene search engine restful service that would allow to index files (MS word, excel, pdf & html) in specific directories and also would take search request and return results with synopsis plus it would return documents with highlighted hits.
