+ This example schema is the recommended starting point for users.
+ It should be kept correct and concise, usable out-of-the-box.

+
+ 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.

+       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...)
+       1.6: useDocValuesAsStored defaults to true.

+
+    <!-- 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 is
+       recommended (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 are currently only supported by StrField, UUIDField, all
+       *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.
