The generation of indexes we generally use the data in the database as the data source. But the data in the database is constantly changing, the data of the database c
The first two articles briefly introduce the application of lucid and the core extension of SOLR. Now we will briefly look at how the interface presented to the front-end based on SOLR is implemented. This part of lucid providesSource codeSo it looks more convenient.

Analysis of front-end application of full-text search
Today personal Coding module test, so spare time to continue to study SOLR, and then incidentally wrote an example, casually, SOLR really not familiar, look forward to know love search friends, and common progress.1. Configure the Schema.xml file [solr\collection1\conf\ directory]Because schema defines some field by de
I recently found a functional solution for searching in a knowledge management system and found a good reference application solution for analysis. I hope that similar applications can communicate with each other.
When talking about full-text retrieval, Lucene's famous name is estimated that people on earth know that after so many years of development, peripheral applications are rich and colorful. SOLR provides a web-based solution based on Lucene
Feature implementation:One: After the project starts, automatically monitors all data models, the data that is queried. Create an indexTwo: dynamic automatic updating of incremental Data Index and maintenance index.This is a project that builds an index based on the data model, the coupling degree is low, the expansibility is high. Different from the general full-text search project with business nature. For example: Common e-commerce business, Consum

about SOLRWhen we sigh similar to Baidu , Google such a powerful search engine, we may also look back to think, we can also do one, although not their NB, but at least in China this society, can imitate is also a skill, come on, Today, let's meet the omnipotent Java people, how they grope for search engines.Legend in a corner of the world, there is a thatched house, which is full of people with the same sur
In Solr, there are 3 options for real-time search①soft commit, which is actually near real-time search, cannot be completely real-time. ②realtimeget, this is real-time, but only supports queries based on the document ID. ③ and the first one are similar, just trigger softcommit.

If you need to retrieve data with latitude and longitude, such as finding a hotel 1000 meters near the current location, an easy way is to get all the hotel data in the database, calculate the distance by latitude, and return the data that is less than 1000 meters away.
This is useful when the data is small, but the efficiency of the retrieval is low when the volume of data is large, and this article describes the use of SOLR's spatial query for spatial sear
As a search, our traditional method (positive index) starts from the key point, and then finds the specific information that can meet the search conditions in the Key Point information, both search for value through key. Lucene uses inverted indexes to search for keys. In Chinese full-text
SOLR provides a JSON-formatted search result, but how is it called in a cross-domain scenario?

SOLR has a thick package outside lucene, mainly to simplify two development and provide some proven solutions.Lucene is a full-text search that matches the field of the document in the index, returns the document, and gets the result set of the query.Lucene is more like an SDK. There is a complete API family and the corresponding implementation. You can use these to implement advanced queries in your own ap

General steps for creating an index in solrj:
1) create a solrserver object, which is used to manage indexes.
2) create a solrinputdocument object, that is, a document object, and add fields to the Document Object.
3) use the Add method of the solrserver object to add the solrinputdocument object and create an index.
4) Call The COMMIT () method of the solrserver object to submit the index.
For example:
Httpsolrserver HSS = new httpsolrserver ("http: // localhost: 8080/
Solrcloud is a distributed search solution based on SOLR and zookeeper.
CodeLibrary to become the distributed Deployment Solution for the next release (estimated to be 4.0. Cloud uses zookeeper as the configuration center to store distributed node information. Each node still uses an HTTP connection to obtain query results. Premise: the index has been created and split into slices, that is, shard. The foll
