SOLR Learning Summary (iii) SOLR Web management Backend

The previous talk about SOLR's installation, according to the rationale, this time should be about. NET and the contents of the database, C # How to manipulate SOLR indexes and so on. But I would like to start with some basic content, such as SOLR query parameter usage instructions and the use of SOLR's own web management system. Only first understand the basic content of SOLR, follow-up learning SOLR C # and database operations, will not be laborious. I have just started to configure SOLR, directly to the SOLR client, write the corresponding test code, but because do not know an update request specifically what parameters are required, what are the meaning of each parameter, so that the basic problems encountered in various SOLR, do not know where the problem? Lesson.

SOLR Web Management Backend

Visit Homepage: http://localhost:8080/solr/#/

1. Dashboard Dashboard, showing SOLR's basic information, including the SOLR version, including system memory and JVM memory usage, JVM parameters, etc.

　　　　　　

2. Logging SOLR's run log to see if SOLR runs with warnings or exceptions for timely processing

3. Core Admin Index Library Management, this interface is very important, which makes multi-core configuration, index library optimization, etc., becomes very simple;
Key features include: Addcore (add core, index Library), Unload (unload Core), Rename (rename core), Optimize (optimized index library).

4. Core Selector key selector, select the index library to manipulate

　　　　　　

1. Overview (Overview): Look at the index, for example: see if num docs is increasing in number. Contains basic statistics such as the current number of documents, and instance information such as the current core configuration directory;

2. Analysis: Check the word segmentation effect, which is used to diagnose the query/index problem of potential text analysis. Note that the FieldType needs to be selected to be consistent with the parsed content type.

3. Query: This is a query interface, with more, used to query the index of the document, including whether the existence, sorting is correct, and so on. The relevant query parameters are described later.

　　　　　　　

4. Schema (current index library definition), displays the current schema's configuration file, that is, the contents of the schema.xml, such as: You can see the configuration fields in Schema.xml, and so on.

5. Documents (index documents) index related operations, additions, modifications, deletions, etc., for example we want to add an index

A. To add the relevant fields to the Schema.xml profile in Solr's D:\solr_home\mycore1\conf, for example: <field name= "title" Type= "string" indexed= "True" stored= "true" required= "true" multivalued= "false"/>

B. On the following page, select/update, document format, select JSON, and submit. So the index is added up. The modification is as/update as the increment, and is deleted as/delete.
