The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. I got the list of unique values for my field. The Apache Hadoop® project develops open-source software for reliable, scalable, distributed computing. Somehow, I got the doc_values enabled and I’m trying to do term aggregation to solve same business problem.
My business problem is “get all the distinct values/terms of a field (type: keyword)”.Īs you suggested, I can do with elasticsearch terms aggregation only when the field has doc_values enabled. Thanks for your quick reply Alessandro Benedetti. – You don’t need Indexing time boosting per field – You don’t need to boost short field contents The norms data structure will not be built – You want to use the Posting Highlighter.Ī fast version of highlighting that uses the posting list instead of the term vector. The posting list for each term will contain the term offsets in addition. – You do need to search in your corpus with phrase or positional queries. The posting list for each term will contain the term positions in addition.Ġ : 1 :, 1 : 2 :, 2 : 1 : To borrow an analogy from Greek mythology, Apache Lucene is the Cronus of search: it has spawned one of the most dominant rises in open source software.
– You do need scoring to take Term Frequencies in consideration The posting list for each term will simply contain the document Ids ( ordinal) and term frequency in the document. Lucene.Net is a port of the Lucene search library, written in C and targeted at. You don’t need score to be affected by the number of occurrences of a term in a document field. – You don’t need to search in your corpus with phrase or positional queries. The posting list for each term will simply contain the document Ids ( ordinal) and nothing else. You don’t need to search in your corpus of documents.
