First, let’s begin by creating a new project in Visual Studio (or JetBrains Rider, in my example below). It took 3 hours to index 12 thousand files. To sum up, Tika is a great solution but it requires a lot of code-writing and fine-tuning, especially for edge cases: for Tika it's weird PDF's and OCR. NEST is a high-level SDK for interacting with Elasticsearch that we will use to help perform our searches. To save resources in the process of indexing a PDF file for Elasticsearch, it’s best to run pipelines and use the ingest_attachment method. This functionality can be extremely helpful for implementing full text searches for various types of documents leveraging Elasticsearch analyzers and language plugins. Elasticsearch is document oriented, meaning that it stores entire object or documents. It’s really pretty easy, but small matter of programming (SMOP). NEST exposes the index and bulk APIs of Elasticsearch as methods, to enable indexing of single or multiple documents. Apache Tika is an open-source toolkit that detects and extracts metadata and text from numerous file types. List the software requirements to install Elasticsearch?
