![]() ![]() So I was just wondering if adding an hitcollector would give us some additional performance. Fast, general-purpose grammar-based tokenizer StandardTokenizer implements the Word Break rules from the Unicode Text Segmentation algorithm, as specified in Unicode Standard Annex 29. Doing so can slow searches by an order of Apache Lucene is a high-performance, full-featured text search engine library. IndexReader.document(int) on every document Any help would be much appreciated!įor good search performance, implementations of this method should not Early termination now uses a single shared global hit counter across multiple search threads for one query, reducing the total cost for the query. When the query is single-threaded, because you did not pass an Executor to IndexSearcher, that one query thread must visit all segments sequentially. The algorithm for grouping small segments into slices (thread work units) has improved. A Lucene index is segmented, which makes searching it an embarassingly parallel problem: each query must visit all segments in the index, collecting their globally competitive hits. Early search engines were not able to incrementally. ![]() Improved overall apache lucene searching performance update#I've followed every suggestion in the Lucene Wiki but the search is still too slow with large indexes. Lucene now also uses the incoming (calling) thread to help with concurrent searching. Lucenes index merging algorithm is an elegant solution to the inverted index dynamic update problem. I have tried to get a hitcollector in but ended up with confusion. I am looking for a way to improve the search performance of my application. TopDocs hits = (bQuery, null, 1000)Īnd this part would be the function call: ScoreDoc docs = null ĭocs = s.KeywordSearch(keyword, category,, null, null).ToList(), 1000įoreach (ScoreDoc d in docs.Take(maxResult))ĭocument doc = (d.doc) įrom what I understand it would not be advisable to get documents from the searchresults using Searcher.Doc but to have a hitcollector. Is it possible to reduce search time with the use of Lucene's Hitcollector and if so, how would this be properly implemented in the following situation? // search login here ie.īQuery.Add(qbVendor.Parse(vendor.ToLower()), ) īQuery.Add(qbWebsite.Parse(website.ToLower()), ) 3.1 Introduction to Apache Lucene For the following sections we give some general information about the tech-niques and features of Apache Lucene a high-performance, full-featured text search engine library written entirely in Java that is suitable for nearly any appli-cation requiring full-text search, especially cross-platform. ![]()
