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.

I need to perform several lucene queries on a column of text within a CSV. The output must include a binary output that indicates if the text within a cell contains or does not contain each lucene search string. Ideally, I would like to be able to replicate this process in the future for non-technical analysts. For this reason, I believe a connection between Solr and Rapidminer would be a user friendly option, but I am open to other methods for executing this. Thank you very much! An example of the tags is here: An example of the data is here (and attached):
