Goutham Veeramachaneni	2fa647f50b	Fix missing postings in Merge and Intersect (#77) ... * Test for a previous implematation of Intersect Before we were moving the postings list everytime we create a new chained `intersectPostings`. That was causing some postings to be skipped. This test fails on the older version. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in> * Advance on Seek only when valid. Issue: Before in mergedPostings and others we advance everytime we `Seek`, which causes issues with `Intersect`. Take the case, where we have a mergedPostings = m merging, a: {10, 20, 30} and b: {15, 25, 35}. Everytime we `Seek`, we do a.Seek and b.Seek. Now if we Intersect m with {21, 22, 23, 30}, we would do Seek({21,22,23}) which would advance a and b beyond 30. Fix: Now we advance only when the seeking value is greater than the current value, as the definition specifies. Also, posting 0 will not be a valid posting and will be used to signal finished or un-initialized PostingsList.

Tomasz Elendt	d7ad9d2679	Fix various postings implementations ... * newIntersectPostings and newMergePostings should not advance passed postings automatically. * listPostings and bigEndianPostings should not panic with index out of range when At() is called before Next()/Seek(). * Seek() call should advance listPostings/bigEndianPostings.	8 years ago
