		CHANGELOG

		0.1 : first release

		0.2 : added preserveOriginal="1" for text field type in the index analyzer and catenateWords="1" for the query analyzer

		0.3 : changed language for SnowballPorterFilterFactory to language="German2" (index/query) in the text field type

		0.4 : added solr.ASCIIFoldingFilterFactory filter (index/query) in the text field type

		0.5 : added long_keyword field type, to be used for objIdentifiers

		0.6 : added field types for spellchecking

		0.7 : added parameter for text field type

		0.8 : added field _version_, needed by Solr 4.0.0 for the transaction log

		0.9   : added type: text_en_splitting

		0.91  : added type: ngramtext

		0.92  : added schema optimizations, removing unnecessary stored fields

		0.93  : added attribute preserveOriginal="1" to fieldtype ngramtext (query analysis) to improve matches

		0.94  : updated and simplified ngramtext fieldtype

		0.95  : update to solr 4.4, removed attribute "compress" from field definition, ngramfield doesn't support NGramFilterFactory anymore

		0.96  : update to solr 4.9

		0.97  : introduced field type string_ci supporting case insensitivity.

		1.0   : updated to solr 6.6.0

			<!-- Valid attributes for fields:

			 name: mandatory - the name for the field

			 type: mandatory - the name of a field type from the

			   fieldTypes 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 (required, if you are using *Point fields) for faceting,

			   grouping, sorting and function queries. 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, all Trie*Fields and *PointFields,

			   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.

		 the requestDispatcher, then the Request Handler is dispatched based on

		 the qt parameter.  Handlers without a leading '/' are accessed this way

		 like so: http://host/app/[core/]select?qt=name  If no qt is

		 given, then the requestHandler that declares default="true" will be

		 used or the one named "standard".

		 If a Request Handler is declared with startup="lazy", then it will

		 not be initialized until the first request that uses it.

		 http://wiki.apache.org/solr/SearchHandler

		 For processing Search Queries, the primary Request Handler

		 provided with Solr is "SearchHandler" It delegates to a sequent

		 of SearchComponents (see below) and supports distributed

		 queries across multiple shards

	  -->

	<requestHandler name="/select" class="solr.SearchHandler">

		<!-- default values for query parameters can be specified, these

			 will be overridden by parameters in the request

		  -->

		<lst name="defaults">

			<str name="echoParams">explicit</str>

			<str name="q.op">AND</str>

			<int name="rows">10</int>

			<!-- <str name="df">text</str> -->

		</lst>

		<!-- In addition to defaults, "appends" params can be specified

			 to identify values which should be appended to the list of

			 multi-val params from the query (or the existing "defaults").

		  -->

		<!-- In this example, the param "fq=instock:true" would be appended to

			 any query time fq params the user may specify, as a mechanism for

			 partitioning the index, independent of any user selected filtering

			 that may also be desired (perhaps as a result of faceted searching).

			 NOTE: there is *absolutely* nothing a client can do to prevent these

			 "appends" values from being used, so don't use this mechanism

			 unless you are sure you always want it.

		  -->

		<!-- "invariants" are a way of letting the Solr maintainer lock down

			 the options available to Solr clients.  Any params values

			 specified here are used regardless of what values may be specified

			 in either the query, the "defaults", or the "appends" params.

			 In this example, the facet.field and facet.query params would

			 be fixed, limiting the facets clients can use.  Faceting is

			 not turned on by default - but if the client does specify

			 facet=true in the request, these are the only facets they

			 will be able to see counts for; regardless of what other

			 facet.field or facet.query params they may specify.

			 NOTE: there is *absolutely* nothing a client can do to prevent these

			 "invariants" values from being used, so don't use this mechanism

			 unless you are sure you always want it.

		 <searchComponent name="debug"     class="solr.DebugComponent" />
