| 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 |

| |
| 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 StreamingUpdateSolrServer |
| java client. |
| - Remember to run the JVM in server mode, and use a higher logging level |
| that avoids logging every request |

| <fields> |
| <!-- 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. |
