What is phrase search Solr?

Phrase match: A simple way by which we can achieve exact matching in Solr is by using the default string type. It is exact phrase matching. the string is a useful type for facet where we search the index by using the text pulled from the index itself.

How do I search for a query in Solr?

The main query for a solr search is specified via the q parameter. Standard Solr query syntax is the default (registered as the “lucene” query parser). If this is new to you, please check out the Solr Tutorial. Adding debug=query to your request will allow you to see how Solr is parsing your query.

What is Solr fuzzy search?

The Solr fuzzy search syntax uses the Damerau-Levenshtein Distance algorithm to determine similarity of spelling based on distance. The default distance is 2. Change the distance by specifying 0-2 after the tilde (Kenya~1).

How do you use FQ in Solr?

The fq filter query parameter in a query to Solr search is used to filter out some documents from the search result without influencing the score of the returned documents. Queries with fq parameters are cached.

What is shard in solr?

Solr sharding involves splitting a single Solr index into multiple parts, which may be on different machines. When the data is too large for one node, you can break it up and store it in sections by creating one or more shards, each containing a unique slice of the index.

How does Solr search work?

Solr works by gathering, storing and indexing documents from different sources and making them searchable in near real-time. It follows a 3-step process that involves indexing, querying, and finally, ranking the results – all in near real-time, even though it can work with huge volumes of data.

What is full-text search in Solr?

Solr is a mighty tool to perform full text search with many of extra features, such as (various kinds of) facets, "Did you mean?" functionality and highlighting with suitable selection of text snippets for an extract. Implementing a fully featured Solr search can be involved and time consuming.

Which feature is supported in Solr search?

Solr also supports a feature called MoreLikeThis, which enables users to submit new queries that focus on particular terms returned in an earlier query. MoreLikeThis queries can make use of faceting or clustering to provide additional aid to users.

Which is better SOLR or Elasticsearch?

Solr has more advantages when it comes to the static data, because of its caches and the ability to use an uninverted reader for faceting and sorting – for example, e-commerce. On the other hand, Elasticsearch is better suited – and much more frequently used – for timeseries data use cases, like log analysis use cases.

Does SOLR support fuzzy search?

Solr supports fuzzy search based on Damerau-Levenshtein Distance or Edit Distance algorithm.

Is fuzzy search good?

Fuzzy search is more powerful than exact searching when used for research and investigation. Fuzzy search is very useful when researching unfamiliar, foreign-language, or sophisticated terms, the correct spellings of which don't seem to be widely known.

What are filters in Solr?

Filters examine a stream of tokens and keep them, transform them or discard them, depending on the filter type being used. You configure each filter with a <filter> element in schema.xml as a child of <analyzer> , following the <tokenizer> element.

What is shard and replica in Solr?

Collection − A cluster has a logical index that is known as a collection. Shard − A shard is portion of the collection which has one or more replicas of the index. Replica − In Solr Core, a copy of shard that runs in a node is known as a replica.

How many shards are there in Solr?

Best Practice: Use one shard!

Shards disable Managed Solr's backup features. (Custom backups can be arranged for premium customers.) If your index can fit comfortably on one server, then use one shard. This is Solr's default behavior.

What is difference between core and collection in Solr?

Collection is a logical index spread across multiple servers. Core is that part of server which runs one collection. In non-distributed search, Single server running the Solr can have multiple collections and each of those collection is also a core.
