documents comply with the query? Real queries are not performed in the score () method. From the perspective of data extraction, modern search engines extract a list of documents that meet the term from inverted index. I personally know what is in inverted index. All the documents obtained by the specified keyword are completed using the inverted index data structure, this is also the core of the search pr

best value, so what we can do is to change the boosting at 1.1 points, and then observe in the actual detection how much it will play a role in the search results to adjust In general, there is no need to use boosting, because if it is not good, you will mess up the search, and if it is a separate field for bossting, this field can also be used in advance to achieve a similar effect.Indexing date Date is o

SOLR has a thick package outside lucene, mainly to simplify two development and provide some proven solutions.Lucene is a full-text search that matches the field of the document in the index, returns the document, and gets the result set of the query.Lucene is more like an SDK. There is a complete API family and the corresponding implementation. You can use these to implement advanced queries in your own ap

1. A brief analysis, in the middle of Lucene, is the process of converting a field (field) to the most basic index representation Unit-item (TERM). The value of the item is called the Vocabulary Unit (token). For English, this process has experienced the extraction of words, the removal of punctuation, letters to lowercase, remove the word stop, stem reduction and so on. The corresponding relationship is shown in Figure 1-1. Term's analytical process
