| 13 | Indexes specify what parts of the collection are searchable. This section explains how to add and remove indexes, and set a default index. Under "Design Sections", click "Search Indexes".
|
|---|
| 14 | <p></p>
|
|---|
| 15 | To add an index, type a name for it into the "Index Name" field. Select which
|
|---|
| 16 | of the possible information sources to index by clicking the checkboxes beside
|
|---|
| 17 | them. The list shows all the assigned metadata elements, as well the full
|
|---|
| 18 | text. Having selected the data sources, choose the granularity of the index,
|
|---|
| 19 | using the "At the level" menu. Once these details are complete, "Add Index"
|
|---|
| 20 | becomes active (unless there is an existing index with the same settings).
|
|---|
| 21 | Click it to add the new index.
|
|---|
| 22 | <p></p>
|
|---|
| 23 | To edit an index, select it and change the index details, then click "Replace Index".
|
|---|
| 24 | <p></p>
|
|---|
| 25 | To remove an index, select it from the list of assigned indexes and click
|
|---|
| 26 | "Remove Index".
|
|---|
| 27 | <p></p>
|
|---|
| 28 | To create an index covering text and all metadata, click "Add All".
|
|---|
| 29 | <p></p>
|
|---|
| 30 | The default index, the one used on the collection's search page, is tagged with
|
|---|
| 31 | "[Default Index]" in the "Assigned Indexes" list. To set it, select an index
|
|---|
| 32 | from the list and click "Set Default".
|
|---|
| 33 | <p></p>
|
|---|
| 34 | If advanced searching is enabled (via the Search Types view), the index controls are different. There is a new pseudo-data source "allfields" which provides searching across all specified indexes at once. Levels are not
|
|---|
| 35 | assigned to a specific index, but apply across all indexes: thus indexes and
|
|---|
| 36 | levels are added separately. "Add All" creates a separate index for each metadata field in this mode.
|
|---|
| 37 | <p></p>
|
|---|
| 38 | The name of each index will default to the source name. To change the name, select an index, change its details, and click "Replace Index".
