Indexing

Whether a repository is indexed is not of your interest, and usually, you don’t need to know it. However, in some cases, indexing capabilities can be used to define more precise queries. For example, wildcards can only be used if the repository is indexed, if not, they are skipped. In Documentum version 6.7, two index servers are supported: Fast and xPlore. The behavior of search operators may be slightly different between the two. For example, when searching for several terms separated with spaces, the spaces are interpreted as an OR operator with Fast index server, while they are interpreted as an AND operator with xPlore index server. If you want to run complex queries, consult the system administrator for details on the indexing configuration of the repository. The section Index a repository, provides more information about indexing.

Relevancy ranking

The system administrator can specify a bonus ranking for specific sources, add weight for a specific property value or improve the score for a specific format.

Presets

The system administrator can define a preset to restrict the list of available types in the Advanced search page. Presets can be different from one repository to another. If you select only external sources, the preset of the current repository applies.

Customization of the Advanced search page

The Advanced search page can be fully customized to guide you in running queries. For this reason, all the options described in this guide may not be available, and other may appear to narrow and/or condition your queries.

Maximum number of results

The maximum number of results is defined at two levels. By default, the maximum number of results, taking all sources together, is 1000 and 350 results per source. However, your system administrator can modify these parameters. When querying an external source, the maximum number of results also depends on the configuration set for this source. Results are selected according to their ranking. This way, you always get results with the best ranking; other results are skipped.

Case-sensitivity

If the repository is indexed, queries are case-insensitive by default, even using quotation marks. If the repository is not indexed, then queries are case-sensitive. However, for non-indexed repositories, case-sensitivity can be turned on, and off by the system administrator.

Grammatical normalization (lemmatization)

When you do not use quotation marks, Webtop displays files that include variations of the words you typed in addition to the exact words. These variations are based on the word’s root. This behavior depends on the configuration of the full-text engine, and is called grammatical normalization. The variations are based on the grammatical context of the word. For example, a search for the verb "run" also finds "ran" but does not find the noun "running."

External sources

When querying an external source, the results displayed in Webtop depend partly on the configuration of this source. For example, if the source does not return information on dates, then dates cannot be filtered.

Multiple repositories

As for external sources, the results depend on the configuration of each repository. For example, the indexing may be set differently on various repositories.
