Viktor Lofgren d986f90074 (index) Fix consistency between RandomFileAssembler implementations
The RandomFileAssembler implementations, introduced in commit 53c575db3f were all acting subtly differently.  The RWF implementation wrote BigEndian longs instead of the native endianness used by the other implementations (and expected by the index construction code), further the mmap implementation exposed a bug in LongArray.write() that caused it to create a larger file than necessary.

A test was built to ensure the output of these implementations is equivalent.

Libraries

These are libraries that are not strongly coupled to the search engine's business logic. These libraries may not depend on features, services, processes, models, etc.

NOTE: These libraries are co-licensed under the MIT license.

Libraries

  • The array library is for memory mapping large memory-areas, which Java has bad support for. It's designed to be able to easily replaced when Java's Foreign Function And Memory API is released.
  • The btree library offers a static BTree implementation based on the array library.
  • language-processing contains primitives for sentence extraction and POS-tagging.
  • The message-queue library.

Micro libraries

  • easy-lsh is a simple locality-sensitive hash for document deduplication
  • guarded-regex makes predicated regular expressions clearer
  • big-string offers seamless string compression
  • random-write-funnel is a tool for reducing write amplification when constructing large files out of order.
  • next-prime naive brute force prime sieve.
  • braille-block-punch-cards renders bit masks into human-readable dot matrices using the braille block.
