[Java] Solr video tutorial and solr video tutorial for enterprise distributed search platform Course BackgroundDistributed search engines that are highly available, scalable, and fault-tolerant. Solr is a high-performance full-text search server developed by Java 5 based on Lucene. At the same time, it is expanded to provide a richer query language

to the sort mechanism that SOLR has defaulted on, default VSM, default Sortbyfield, default function collection including their combinations,The default booleanquery, Phrasequery, Luceneparser, Dismax parser, and so on, cannot meet the ordering requirements.Then you need to unveil and introduce your own sort.(3) sequencing is a dynamic processAbsolutely not once set, permanently valid.

Q: for pinyin and Pinyin first letter support, when you search for goods, if you want to enter the pinyin and pinyin first letter to give the product information, how to do?There are 2 ways to implement them, but they are in fact corresponding. using Lucene to achieve 1. Build an index, more than one index field, that is, pinyin and pinyin first letter of the 2 fields. A field that is merged.(Pinyin and pinyin initials can be obtained by Pinyin4j.jar. Convert the fields you want to searc

1. first assume that my data fields are: Name, tel, address preset Search is the Name field, if the data to be searched is exactly the name field, you do not need to specify the search field name.　　2. Query Rules:If you want to query a specific field (not a preset field), precede the query with the field name plus ":" (No "sign") symbol,For example: Address: tel:88xxxxx1, Haidian District, Beijing Software Park1>.

A brief description of Solr master-slave cluster configuration and a brief description of solr master-slave Cluster Solr clusters are mainly divided into master-slave and SolrCloud clusters. It is applicable to read-dominated scenarios. SolrCloud is suitable for scenarios with large data volumes and updates from time to time. Therefore, the master-slave configura

SOLR I am still a rookie, writing these articles is just a record of recent time to learn SOLR experience. What is SOLR?Recently, when I was learning solr, I had always seen a phrase that SOLR is an out-of-the-box search server for use in the enterprise, based on Lucene. At

Full-text search engine Solr, full-text solr Solr is an independent enterprise-level search application server that provides APIs similar to Web-service. You can submit an XML file of a certain format to the search engine server through an http request to generate an index. You can also submit a search request through the Http Get operation and obtain the return

As the search engine function has a large number of functional requirements that require search engines in the portal community to improve user experience, there are currently a centralized solution for implementing search engines: Implement intra-site search by using Lucene's own encapsulation. Large workload and scalability, not used. Call APIs of Google and Baidu to implement intra-Site Search It is too dead to bind with a third-party search engine to meet the business expansion nee

Over the past two days, I have been wondering whether to use Lucene for search applications or SOLR for search applications. Lucene only provides one queryable package. The advantage of using it for search is that I can use the corresponding functions provided by the application as needed. SOLR itself is a Lucene-based application that encapsulates Lucene, which is equivalent to development on the second la
