In all synonym rules, the IDX rule document has the same basic form.
The table shows all the fields that you must include in the IDX file for synonym rules. The value of the
CONCEPT fields determines whether the rule is a synonym, hyponym, or hypernym rule.
|Field||Description||Content type or value|
||The reference for the rule.||String|
||The title of the rule.||String|
||The type of the HPE QMS rule.||
||The AgentBoolean expression used to match the original query text.||Boolean matching expression|
||A list of words to match in the query text.||Comma-separated list of words or phrases.|
||The expanded query text that replaces the matched query text.||Replacement string.|
||The databases to query.||String|
||(Optional) A Boolean value that specifies whether to replace the whole query text with the
When a query matches the rule, HPE QMS replaces any of the specified
KEYWORDS that exist in the text with the value in the
If you set
KEYWORDS field is not required, and HPE QMS always replaces the whole query text.
KEYWORDS can be a list of individual words or phrases. Separate each word or phrase with a comma. For example:
#DREFIELD KEYWORDS="Software Development Kit,SDK"
When you use phrases, the entire phrase must match the query text for HPE QMS to apply the rule. For example, software does not match this keyword example.
If your keyword phrase contains a comma, you must percent-encode it in the rule. For example:
#DREFIELD KEYWORDS="Hello%2C World,Goodbye"
HPE QMS does not apply synonyms to exact phrase searches. For example, if a user searches for
"software development kit" (including the quotation marks), HPE QMS does not modify the query.
CONCEPT can be any valid query text string, which HPE QMS inserts into the query text in place of the matching keyword or phrase. For example:
#DREFIELD CONCEPT=""Software Development Kit" OR SDK"
HPE QMS surrounds multiple-word query strings with brackets when it modifies the query. For example, if a user searches for
SDK OR API, HPE QMS expands the query to (
"Software Development Kit" OR SDK) OR API.
You can use the
SYNONYM query operator in the
CONCEPT field. This operator contains a list of synonymous terms. When IDOL Server processes this query, it finds results that contain any of the synonymous terms. For result weighting, IDOL Server treats all the synonyms as if they are a single term, which can improve the result ordering. For example:
#DREFIELD CONCEPT="SYNONYM("Software Development Kit" SDK)"
For more information, refer to the IDOL Server Administration Guide.
You can use the
$QUERYTEXT$ template string in the
CONCEPT field, to insert the original query text. For example, if you have a Wildcard in your AgentBoolean rule, you can include the query text in
CONCEPT to capture all possible variations of the wildcard expression without enumerating them individually. For example:
#DREFIELD QMSAGENTBOOL "Al* AND Smith" #DREFIELD KEYWORDS "Al Smith" #DREFIELD CONCEPT "(Alexander Smith) OR ($QUERYTEXT$)"
You might want to use this template string with the
SYNONYMREPLACE field, to avoid repeating the original text in the final modified query.
You can use an appropriate combination of
CONCEPTS to create synonym, hyponym, and hypernym rules.
To create a synonym rule
KEYWORDS field to a list of all the synonymous terms, and set the
CONCEPT field to the same list.
HPE QMS expands any query that matches one keyword to include all the other keyword terms.
To create a hyponym rule
KEYWORDS field to the parent term, and set the
CONCEPT field to the list of terms that the parent term describes (the hyponyms).
HPE QMS alters a query that matches the parent term to include all the hyponyms, but not the original term.
To create a hypernym rule
KEYWORDS field to a list of the terms that the hypernym describes, and set the
CONCEPT field to the parent term (hypernym).
HPE QMS alters any query that matches one of the list of child terms to query for the hypernym (and not the original term).
