First, make sure you have Java installed on your system.Which means you can index any type of field in each document in Apache Solr. Lucene does not have common global schema. Each document can contain multiple fields. So when you index your node to Apache Solr, it is considered as a document. In Drupal, each node is considered as a document. This allows for efficient and flexible storage and retrieval of data. Storage SchemaĪpache Solr uses a document-based storage schema and stores every piece of data as a separate document within a collection. This makes it easy and faster to fetch the particular document only. Instead of looking for the document, it first looks into the index to see which documents do the words “Chocolate” and “Cake” fall under. So when someone searches for the term “Chocolate Cake”, the engine looks into the index. These are called Stop words which will not be indexed or searchable by Solr. You will notice that words like “I”, “love” are not tokenized. The way it is tokenized is as shown in the 2nd column of the below table. Inverted index is a way in which Solr builds the index. All those tokens will be indexed to the inverted index. Without indexing, the search engine requires more time to scan every documentįirst, the document will be analyzed and split into tokens.Fast and accurate information retrieval (collects, parses and stores).Searching is the process of consulting the search index and retrieving the doc matching the query. The texts are first broken into tokens (atomic elements). Search engines don't index data directly. Indexing is the processing of original data into highly efficient cross-reference lookup to facilitate rapid search. What is Indexing?Īll search engines begin with indexing. It also supports many languages other than English like German, French, Spanish, Chinese, Japanese, and more. It is versatile, powerful, accurate, and works on an efficient search algorithm.Īlthough known for its full-text search capabilities, Lucene can also be used for document classification, data analysis and information retrieval.
