Searches one or more Verity collections.
A collection must be created and indexed before this tag can return search results.
A collection can be created in these ways:
If you use a native Verity tool to create a collection, it must be registered. A collection can be registered with ColdFusion in the following ways:
A collection can be indexed in the following ways:

Attribute |
Req/Opt |
Default |
Description |
---|---|---|---|
name |
Required |
|
Name of the search query. |
collection |
Required |
|
One or more collection names. You can specify more than one collection unless you are performing a category search (that is, specifying category or categoryTree). |
category |
Optional |
|
A list of categories, separated by commas, to which the search is limited. If specified, and the collection does not have categories enabled, ColdFusion throws an exception. |
categoryTree |
Optional |
|
The location in a hierarchical category tree at which to start the search. ColdFusion searches at and below this level. If specified, and the collection does not have categories enabled, ColdFusion throws an exception. Can be used in addition to the category attribute. |
criteria |
Optional |
|
Search criteria. Follows the syntax rules of the type attribute. If you pass a mixed-case entry in this attribute, the search is case-sensitive. If you pass all uppercase or all lowercase, the search is case-insensitive. Follow Verity syntax and delimiter character rules; see "Using Verity Search Expressions" in the ColdFusion Developer's Guide. |
contextBytes |
Optional |
300 |
The maximum number of bytes Verity returns in the context summary. |
contextHighlightBegin |
Optional |
<b> |
The HTML to prepend to search terms in the context summary. Use this attribute in conjunction with contextHighlightEnd to highlight search terms in the context summary. |
contextHighlightEnd |
Optional |
</b> |
The HTML to append to search terms in the context summary. Use this attribute in conjunction with contextHighlightBegin to highlight search terms in the context summary. |
contextPassages |
Optional |
0 |
The number of passages/sentences Verity returns in the context summary (that is, the context column of the results). The default i s 0, which disables context summary. |
language |
Optional |
english |
Deprecated. This attribute is now ignored and the language of the collection is used to perform the search. |
maxRows |
Optional |
all |
Maximum number of rows to return in query results. |
previousCriteria |
Optional |
|
The name of a result set from an existing set of search results. Verity searches the result set for criteria without regard to the previous search score or rank. Use this attribute to implement searching within result sets. |
startRow |
Optional |
1 |
First row number to get. |
status |
Optional |
|
Specifies the name of the structure variable into which ColdFusion places search information, including alternative criteria suggestions (spelling corrections). For a list of keys in this structure, see Status structure keys. |
suggestions |
Optional |
never |
Specifies whether Verity returns spelling suggestions for possibly misspelled words. Use one of the following options:
There is a small performance penalty for retrieving suggestion data. |
type |
Optional |
simple |
Used to specify the parser that Verity uses to process the criteria.
For more information, see "Using Verity Search Expressions" in the ColdFusion Developer's Guide. Also see your Verity documentation. |
The cfsearch tag returns a query object whose columns you can reference in a cfoutput tag. For example, the following code specifies a search for the exact terms "filming" or "filmed":
<cfsearch name = "mySearch" collection = "myCollection" criteria = '<WILDCARD>`film{ing,ed}`' type="explicit" startrow=1 maxrows = "100"> <cfdump var = "#mySearch#>
In this example, the single-quotation mark (') and backtick (`) characters are used as delimiters; for more information, see "Using Verity Search Expressions" in the ColdFusion Developer's Guide.
To optimize search performance, always specify the maxrows attribute, setting it to a value that matches your application's needs. A value less than 300 helps to ensure optimal performance.
Adobe does not recommend using the cflock tag with this tag; Verity provides the locking function. Using the cflock tag slows search performance.
The cfsearch tag result columns
Variable |
Description |
---|---|
context |
A context summary containing the search terms, highlighted in bold (by default). This is enabled if you set the contextpassages attribute to a number greater than zero. |
url |
Value of URLpath attribute in the cfindex tag used to populate a collection. |
key |
Value of the key attribute in the cfindex tag used to populate a collection. |
title |
Value of title attribute in cfindex tag used to populate the collection, including PDF and Office document titles. If a title is not extracted from the document, the tag uses the cfindex title attribute value for each row. |
score |
Relevancy score of document based on search criteria |
custom1, custom2, custom3, custom4 |
Value of custom fields in cfindex tag used to populate a collection. |
size |
The number of bytes in the index document. |
rank |
The rank of this document in the search results. |
author |
Extracted from the HTML, Office, and PDF documents when available. |
type |
The MIME type of the document. |
category |
A list of the categories that were specified for this document when it was indexed. |
categoryTree |
A hierarchical category tree, or serial list of categories, that was specified for this document when it was indexed. Only a single tree is returned. |
summary |
Contents of automatic summary generated by cfindex. |
recordCount |
Number of records returned in record set |
currentRow |
Current row that cfoutput is processing. |
columnList |
List of column names within record set. |
recordsSearched |
Number of records searched. This is the same value for each row in the record set. Corresponds to the searched key in the status structure. |
Variable |
Description |
---|---|
found |
The number of documents that contain the search criteria. |
searched |
The number of documents searched. Corresponds to the recordsSearched column in the search results. |
time |
The number of milliseconds the search took, as reported by the Verity K2 search service. |
suggestedQuery |
An alternative query, as suggested by Verity, that might produce better results. This often contains corrected spellings of search terms. Present only when the suggestions tag attribute criteria is met. |
keywords |
A structure containing each search term as a key to an array of up to five possible alternative terms, in order of preference. Present only when the suggestions attribute criteria is met. |
keywordScore |
A structure in the same format as for keywords, except it also includes Verity-reported weighted values from 0 to .99, in which higher scores indicate better-quality results. |
To permit application users to search Verity collections for nonstandard strings, words, or characters (for example, "AB23.45.67" or "--->") that would otherwise cause an error, you can create a text file that lists these elements and defines their formats for Verity. Name the file style.lex and put copies of the file in these directories:
In the multiserver and J2EE configurations, you install Verity in a separate directory.
