| 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. |

| <!-- attribute "name" is the name of this schema and is only used for display purposes. |

| |
| 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. |

| <!-- field names should consist of alphanumeric or underscore characters only and |
