+Solr:
+====
+Solr is a search platform from apache Lucene. Its major features include powerful full-text search, hit highlighting, faceted search, near real-time indexing, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly reliable, scalable and fault tolerant, providing distributed indexing, replication and load-balanced querying, automated failover and recovery and more.
+
+Solr with DataTorrent:
+=====================
+Solr search platform can be intergrated with datatorrent for variety of purposes for use cases ranging from simple keyword search to ranking, scoring, classification etc.
+
+Solr InputOperator:
+==================
+AbstractSolrInputOperator class takes care of connecting to Solr server and querying it for data during each emitTuples() call. To implement input operator extend AbstractSolrInputOperator and
+implement following functions
+
+1. initializeSolrServerConnector: Refer section SolrServer Initialization.
+2. emitTuple: SolrServer returns data in form of SolrDocument override this method to convert the documents in the POJO objects as per your need.
+3. getQueryParams: Write your search queries which will be invoked during eact emitTuples call to fetch data from Solr Server.
+
+Solr OutputOperator:
+===================
+AbstractSolrOutputOperator class takes care of connecting to Solr server and pushing documents to server. To implement output operator extend AbstractSolrOutputOperator and implement following
+functions
+1. initializeSolrServerConnector: Refer section SolrServer Initialization.
+2. getTuple: Data can flow in any format (e.g. POJO objects) override this method to convert incoming data to SolrInputDocument object so that it could be stored and indexed by Solr.
+
+
+SolrServer Initialization:
+=========================
+Solr supports different server implementations like HttpSolrServer, CloudSolrServer, ConcurrentUpdateSolrServer and LBHttpSolrServer. Also it exposes relevant properties on each of these servers.
+So SolrServer instance needs to be initialized as per business needs, by whoever want to use these operators.
+HttpSolrServerConnector, wrapper over HttpSolrServer, is already in place and can be initialized by providing intialization parameters from dt-site.xml

+ This is the Solr schema file. This file should be named "schema.xml" and
+ should be in the conf directory under the solr home
+ (i.e. ./solr/conf/schema.xml by default)
+ or located where the classloader for the Solr webapp can find it.
+
+ This example schema is the recommended starting point for users.
+ It should be kept correct and concise, usable out-of-the-box.
+
+ For more information, on how to customize this file, please see
+ http://wiki.apache.org/solr/SchemaXml
+
+ PERFORMANCE NOTE: this schema includes many optional features and should not
+ be used for benchmarking. To improve performance one could
+ - set stored="false" for all fields possible (esp large fields) when you
+ only need to search on the field but don't need to return the original
+ value.
+ - set indexed="false" if you don't need to search on the field, but only
+ return the field as a result of searching on other indexed fields.
+ - remove all unneeded copyField statements
+ - for best index size and searching performance, set "index" to false
+ for all general text fields, use copyField to copy them to the
+ catchall "text" field, and use that for searching.
+ - For maximum indexing performance, use the ConcurrentUpdateSolrServer
+ java client.
+ - Remember to run the JVM in server mode, and use a higher logging level
+ that avoids logging every request

+<schema name="example" version="1.5">
+ <!-- attribute "name" is the name of this schema and is only used for display purposes.
+ version="x.y" is Solr's version number for the schema syntax and
+ semantics. It should not normally be changed by applications.
+
+ 1.0: multiValued attribute did not exist, all fields are multiValued
+ by nature
+ 1.1: multiValued attribute introduced, false by default
+ 1.2: omitTermFreqAndPositions attribute introduced, true by default
+ except for text fields.
+ 1.3: removed optional field compress feature
+ 1.4: autoGeneratePhraseQueries attribute introduced to drive QueryParser
+ behavior when a single string produces multiple tokens. Defaults
+ to off for version >= 1.4
+ 1.5: omitNorms defaults to true for primitive field types
+ (int, float, boolean, string...)
+ -->
+
+
+ <!-- Valid attributes for fields:
+ name: mandatory - the name for the field
+ type: mandatory - the name of a field type from the
+ <types> fieldType section
+ indexed: true if this field should be indexed (searchable or sortable)
+ stored: true if this field should be retrievable
+ docValues: true if this field should have doc values. Doc values are
+ useful for faceting, grouping, sorting and function queries. Although not
+ required, doc values will make the index faster to load, more
+ NRT-friendly and more memory-efficient. They however come with some
+ limitations: they are currently only supported by StrField, UUIDField
+ and all Trie*Fields, and depending on the field type, they might
+ require the field to be single-valued, be required or have a default
+ value (check the documentation of the field type you're interested in
+ for more information)
+ multiValued: true if this field may contain multiple values per document
+ omitNorms: (expert) set to true to omit the norms associated with
+ this field (this disables length normalization and index-time
+ boosting for the field, and saves some memory). Only full-text
+ fields or fields that need an index-time boost need norms.
+ Norms are omitted for primitive (non-analyzed) types by default.
+ termVectors: [false] set to true to store the term vector for a
+ given field.
+ When using MoreLikeThis, fields used for similarity should be
+ stored for best performance.
+ termPositions: Store position information with the term vector.
+ This will increase storage costs.
+ termOffsets: Store offset information with the term vector. This
+ will increase storage costs.
+ required: The field is required. It will throw an error if the
+ value does not exist
+ default: a value that should be used if no value is specified
+ when adding a document.
