Full-text searching uses an external search index, which returns an object key as result. The object key is used to run a search query in the database. This database search query takes the permissions of the logged in user into account during the search.

You can change the following configuration settings.

• Common | Indexing | BatchSize: Use this configuration parameter to specify the maximum number of objects to be indexed when indexing runs. The default value is 50000.

• Common | Indexing | DefaultResultLimit: Use this configuration parameter to specify the maximum number of objects to be returned by the search index. The default value is 5000.

During the search, the search strings are broken down into tokens by the search index in use. The search terms are compared with these tokens. The following configuration parameters affect how the text is parsed.

• Common | Indexing | IndexNonTokenChars: This configuration parameter contains the delimiters to be used for separating out the text. You can extend the configuration parameter if certain characters in the search text affect how it is divided up. Default delimiters are ().[].

• Common | Indexing | IndexUseLegacyAnalyzer: If the configuration parameter is set, an alternative tokenizing is also performed. The alternative method of tokenizing is preferable for long tokens. For example, if the string Department_01 is a token, the partial string Department is not considered to be a token.

The following tokens are recognized by the alternative tokenizing.

Table 29: Tokens for alternative tokenizing

Token	Description with example
Words	Sequence of letters and/or numbers
Enumeration	Words linked by punctuation marks (_-/.,) of which at least every second one contains a number. An example is Department_01. Sequences are also decimal numbers and IP addresses.
Email addresses	An email address is often made up of first name, last name, company name and generic top-level domain (for example .com). The order or spelling of the first and last names may vary (for example, use of initials). The special character @ and the punctuation mark (.) not only separate each part of the email address but also links them so that the email address is recognized as a token. Examples of email addresses are Alex.Miller@example.com or A.Meyer@example.com.
Host names	For example website.example.com.
Acronym	For example U. S. A.
Apostrophe	For example O'Name.
@, & surrounded by letters	For example Me&you.
Umlauts such as ä, ö, ü	For example, Alex Müller.
