Search

The Search window allows you to search across all the documents that have been indexed by OmniQ Enterprise. In the Search window, you can enter:

Search Terms – enter your natural language query in the text field. The more information you provide, the more accurate your results are. See “Search strategies”.

After entering your query, click Search.

Not Terms – enter terms to indicate concepts dissimilar to those for which you are searching. Unlike the Boolean NOT operator, documents that contain these terms are still considered for retrieval. However, the number of Not Terms a document contains is considered by the scoring algorithm and its relevance score is downgraded accordingly (based on the weight of the Not Terms it contains).For example, a search for “operating systems” with Not Terms “Windows XP,” would not discount a document for containing the phrase, “opens in a new window.”

Document Groups – limit your search to one or more predefined document groups. Only documents from the chosen document groups are included in the search results.

Number of Results – number of document results to display per page.

Number of Paragraphs – number of document paragraphs to display per result document.

Paragraph scoring is not enabled in version 3.0 of OmniQ Enterprise. Result paragraphs are always the head of the document.

Score Unknown Terms – when true, search terms unknown to the system (for example, terms that do not exist in any indexed document) are considered by the scoring algorithm.

Metadata – three general types of metadata are supported; text, numbers, and dates.

Some metadata fields are document-specific. For example, a Microsoft Word document will have a Word Count, whereas a plain text document will not, and an HTML document will most likely not. Metadata fields that are guaranteed to be searchable for all documents are reliable. When the field searched on is not supported or not present in a document, it is automatically excluded from the results.

Each metadata parameter consists of:

Field – select from the drop-down list of these predefined fields:

**Table 4-1: Predefined metadata fields**
Name	Type	Reliable
Author	TEXT	No
Character Count	INT	No
Client	TEXT	No
Comment	TEXT	No
Company	TEXT	No
Creation Date	TEXT	No
Document Name	TEXT	Yes
Document Origin	TEXT	Yes
Document Path	TEXT	Yes
Document Size (KB)	INT	Yes
Document Type	TEXT	No
Editor	TEXT	No
File Type	TEXT	Yes
Keyword	TEXT	No
Language	TEXT	No
Last Modified	DATE	Yes
Page Count	INT	No
Project	TEXT	No
Publisher	TEXT	No
Reference	TEXT	No
Second Author	TEXT	No
Status	TEXT	No
Subject	TEXT	No
Title	TEXT	No
Word Count	INT	No

Operator – select from the drop-down list. All metadata types support the “equal to” (=) operator, and the number and date types also support “greater than or equal to'”(>=), and the “less than or equal to”(<=) operators.
Value – enter the values for the selected field each document must contain.The values for text types are processed as search text. In other words, search terms are stemmed and augmented through synonyms and acronyms (except file path fields).

The numeric type values are simply numbers and the date type values should be in the format configured by the OmniQ Enterprise System Administrator, for example dd/mm/yyyy. See “Query parsers”.

These parameters are primarily to be used in conjunction with the Search Term and Not Term parameters to refine the search, but you can also use them independently for a simple metadata search (results from a pure metadata search have no meaningful relevance scores).

Metadata Combination Operators – there are two combination operators:

Within Fields – this operator is used when there is at least one metadata parameter with a value that consists of more than one term. When the operator is AND, every term must be present in the document metadata for the match to succeed. When the operator is OR, only one of the terms need exist.

For example, when the parameter is: Author = “John Smith”, the Within Fields operator differentiates the two possible interpretations, which are: Author = “John AND Smith” or Author = “John OR Smith”.

OmniQ Enterprise 3.0 supports only one Within Fields operator, so you cannot perform a metadata search for Author = “John AND (Smith OR Roberts)”.
Across Fields – this operator is used when there are at least two metadata parameters. When the operator is AND, both parameters must succeed for the match to succeed; if the operator is OR, only one of the parameters need succeed.

For example, when the parameters are Author = “Smith,” Title = “Algebra,” the Across Fields operator differentiates the two possible interpretations, which are:
- Author = “Smith” AND Title = “Algebra” or
- Author = “Smith” OR Title = “Algebra”
OmniQ Enterprise 3.0 supports only one Across Fields operator, so you cannot perform a metadata search for multiple Across Fields operators.

Minimum Document Relevance – the minimum relevance ranking a document must score for it to be included within the search results. Documents with scores lower than this minimum threshold are not returned.

Minimum Paragraph Relevance – this feature is not enabled in version 3.0 of OmniQ Enterprise.
