| </h1> |
| <div class="markdown level0 summary"><p><a class="xref" href="Lucene.Net.Search.DocIdSet.html">DocIdSet</a> implementation based on word-aligned hybrid encoding on |
| words of 8 bits. |
| <p>This implementation doesn't support random-access but has a fast |
| <a class="xref" href="Lucene.Net.Search.DocIdSetIterator.html">DocIdSetIterator</a> which can advance in logarithmic time thanks to |
| an index.</p> |
| <p>The compression scheme is simplistic and should work well with sparse and |
| very dense doc id sets while being only slightly larger than a |
| <a class="xref" href="Lucene.Net.Util.FixedBitSet.html">FixedBitSet</a> for incompressible sets (overhead<2% in the worst |
| case) in spite of the index.</p> |
| <p><strong>Format</strong>: The format is byte-aligned. An 8-bits word is either clean, |
| meaning composed only of zeros or ones, or dirty, meaning that it contains |
| between 1 and 7 bits set. The idea is to encode sequences of clean words |
| using run-length encoding and to leave sequences of dirty words as-is.</p> |
| <table><thead><tr><th>TokenClean length+Dirty length+Dirty words</th><th></th></tr></thead><tbody><tr><td>1 byte0-n bytes0-n bytes0-n bytes</td><td></td></tr></tbody></table> |
| <ul><li><strong>Token</strong> encodes whether clean means full of zeros or ones in the |
| first bit, the number of clean words minus 2 on the next 3 bits and the |
| number of dirty words on the last 4 bits. The higher-order bit is a |
| continuation bit, meaning that the number is incomplete and needs additional |
| bytes to be read.</li><li><strong>Clean length+</strong>: If clean length has its higher-order bit set, |
| you need to read a vint (<a class="xref" href="Lucene.Net.Store.DataInput.html#Lucene_Net_Store_DataInput_ReadVInt32">ReadVInt32()</a>), shift it by 3 bits on |
| the left side and add it to the 3 bits which have been read in the token.</li><li><strong>Dirty length+</strong> works the same way as <strong>Clean length+</strong> but |
| on 4 bits and for the length of dirty words.</li><li><strong>Dirty words</strong>are the dirty words, there are <strong>Dirty length</strong> |
| of them.</li></ul> |
| <p>This format cannot encode sequences of less than 2 clean words and 0 dirty |
| word. The reason is that if you find a single clean word, you should rather |
| encode it as a dirty word. This takes the same space as starting a new |
| sequence (since you need one byte for the token) but will be lighter to |
| decode. There is however an exception for the first sequence. Since the first |
| sequence may start directly with a dirty word, the clean length is encoded |
| directly, without subtracting 2.</p> |
| <p>There is an additional restriction on the format: the sequence of dirty |
| words is not allowed to contain two consecutive clean words. This restriction |
| exists to make sure no space is wasted and to make sure iterators can read |
| the next doc ID by reading at most 2 dirty words.</p></p> |
