Solr learning Summary (iii) Solr web management background, solrweb

As mentioned above, the installation of Solr is justified. This time we should talk about. net and database content, and how C # operates Solr indexes. However, I 'd like to talk about some basic content first, such as the solr query parameter usage instructions and the use of the web management system that comes with solr. Only by clearly understanding the basic content of solr, and learning about solr C # And database operations in the future will it be difficult. At the beginning, After configuring solr, I directly went to the solr client to write the test code. However, I do not know which parameters are required for an Update request and what each parameter means, so that I encountered various basic solr problems, I don't know where the problem is? Lessons learned.

5. operations related to the indexes of Documents, such as adding, modifying, and deleting indexes. For example, we want to add an index.

A. in the schema of solr D: \ solr_home \ mycore1 \ conf. add related field fields in the xml configuration file, for example: <field name = "title" type = "string" indexed = "true" stored = "true" required = "true" multiValued = "false"/>

B. Select/update on the following page, select json as the document format, and submit the document by submit. In this way, the index is increased. The modification and addition are both/update and delete as/delete.
