10 best C++ Search Engine libraries in 2022

The use of a library for searching is important in C++ because it allows you to get all the functionality needed for searching from a single location, instead of having to write everything yourself. It helps avoid code duplication and makes your program easier to maintain. C++ Search Engine libraries like typesense, annoy, nanoflann are great for providing fast and easy-to-use search functionality. Typesense is a library for building search engines in C++. It uses the same algorithm as Lucene (the Java library used in Elasticsearch) and has very similar APIs. The biggest difference between Typesense and Lucene is that Typesense uses compile-time reflection to generate code for each indexing operation and uses template metaprogramming to generate code for the query engine. Nanoflann is a C++ template library with bindings in other languages such as C#, Java and Python. The library provides support for approximate nearest neighbors queries on multi-dimensional data sets stored in binary formats such as BLASTER XML or HDF5 with multithreaded computation.
