Solr represents data<\/h2>\n<\/div>\n<\/div>\n
\n
\n
\n
\n
    \n
  • In Apache Solr, a Document is the part of search as well as index.<\/li>\n
  • Index consists of one or more Documents and then Document consists of one or more Fields.<\/li>\n
  • In database terminology,a Document corresponds to a row of the table, and a Field corresponds to a column of the table.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
    \n
    \"apache<\/div>\n<\/div>\n
    \n
    \n

    Schema<\/h2>\n<\/div>\n<\/div>\n
    \n
    \n
      \n
    • Before adding documents to Solr, you need to specify the schema, represented in a file called\u00a0schema.xml<\/code>.<\/li>\n
    • It is not suitable to modify the schema after documents has added to the index.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
      <\/div>\n
      \n
      \n

      The schema declares:<\/h2>\n<\/div>\n<\/div>\n
      \n
      \n
        \n
      1. what kinds of fields there are<\/li>\n
      2. which field should be used as the unique\/primary key<\/li>\n
      3. which fields are required<\/li>\n
      4. how to index and search each field<\/li>\n<\/ol>\n<\/div>\n<\/div>\n
        \n
        \n

        Field Types<\/h2>\n<\/div>\n<\/div>\n
        \n
        \n
          \n
        • In Solr, every field has a type.<\/li>\n
        • Apache Solr expands the variety of field types offered in Lucene.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n

          Examples of basic field types available in Solr include:<\/b><\/p>\n
