Query Language

You can search for any word or phrase on a Web site by typing the word or phrase into a query form and clicking the button to execute the query (for example, the Execute Query button on the sample query form). This section covers the following topics:

Searches produce a list of files that contain the word or phrase no matter where they appear in the text. This list gives the rules for formulating queries:

Boolean and Proximity Operators

Boolean and proximity operators can create a more precise query.

To Search For Example Results
Both terms in the same page access and basic
Or
access & basic
Pages with both the words “access” and “basic”
Either term in a page cgi or isapi
Or
cgi | isapi
Pages with the words “cgi” or “isapi”
The first term without the second term access and not basic
Or
access & ! basic
Pages with the word “access” but not “basic”
Pages not matching a property value not @size = 100
Or
! @size = 100
Pages that are not 100 bytes
Both terms in the same page, close together excel near project
Or
excel ~ project
Pages with the word “excel” near the word “project”

Hints:

Note   The symbols (&, |, !, ~) and the English keywords AND, OR, NOT, and NEAR work the same way in all languages supported by Index Server. Localized keywords are also available when the browser locale is set to one of the following six languages:

Language Keywords
German UND, ODER, NICHT, NAH
French ET, OU, SANS, PRES
Spanish Y, O, NO, CERCA
Dutch EN, OF, NIET, NABIJ
Swedish OCH, ELLER, INTE, NÄRA
Italian E, O, NO, VICINO

Note   The NEAR operator can be applied only to words or phrases.

Wildcards

Wildcard operators help you find pages containing words similar to a given word.

To Search For Example Results
Words with the same prefix comput* Pages with words that have the prefix “comput,” such as “computer,” “computing,” and so on
Words based on the same stem word fly** Pages with words based on the same stem as “fly,” such as “flying,” “flown,” “flew,” and so on

Free-Text Queries

The query engine finds pages that best match the words and phrases in a free-text query. This is done by automatically finding pages that match the meaning, not the exact wording, of the query. Boolean, proximity, and wildcard operators are ignored within a free-text query. Free-text queries are prefixed with $contents.

To Search For Example Results
Files that match free-text $contents how do I print in Microsoft Excel? Pages that mention printing and Microsoft Excel.

Vector Space Queries

The query engine supports vector space queries. Vector queries return pages that match a list of words and phrases. The rank of each page indicates how well the page matched the query.

To Search For Example Results
Pages that contain specific words light, bulb Files with words that best match the words being searched for
Pages that contain weighted prefixes, words, and phrases invent*, light[50], bulb[10], "light bulb"[400] Files that contain words prefixed by “invent,” the words “light,” “bulb,” and the phrase “light bulb” (the terms are weighted)

 

Property Value Queries

With property value queries, you can find files that have property values that match a given criteria. The properties over which you can query include basic file information like file name and file size, and ActiveX properties including the document summary (information) that is stored in files created by ActiveX-aware applications.

There are two types of property queries:

This section covers the following topics:

Property Names

Property names are preceded by either the “at” (@) or number sign (#) character. Use @ for relational queries, and # for regular expression queries.

If no property name is specified, @contents is assumed.

Properties available for all files include:

Property Name Description
All Matches words, phrases, and any property
Contents Words and phrases in the file
Filename Name of the file
Size File size
Write Last time the file was modified

ActiveX property values can also be used in queries. Web sites with files created by most ActiveX-aware applications can be queried for these properties:

Property Name Description
DocTitle Title of the document
DocSubject Subject of the document
DocAuthor The document’s author
DocKeywords Keywords for the document
DocComments Comments about the document

For a complete list of property names, see the List of Property Names later on this page.

Relational Operators

Relational operators are used in relational property queries.

To Search For Example Results
Property values in relation to a fixed value @size < 100
@size <= 100
@size = 100
@size != 100
@size >= 100
@size > 100
Files whose size matches the query
Property values with all of a set of bits on @attrib ^a 0x820 Compressed files with the archive bit on
Property values with some of a set of bits on @attrib ^s 0x20 Files with the archive bit on

Property Values

To Search For Example Results
A specific value @DocAuthor = Bill Barnes Files authored by “Bill Barnes”
Values beginning with a prefix #DocAuthor George* Files whose author property begins with “George”
Files with any of a set of extensions #filename *.|(exe|,dll|,sys|) Files with .exe, .dll, or .sys extensions
Files modified after a certain date @write > 96/2/14 10:00:00 Files modified after February 14, 1996 at 10:00 GMT
Files modified after a relative date @write > -1d2h Files modified in the last 26 hours
Vectors matching a vector @vectorprop = { 10, 15, 20 } ActiveX documents with a vectorprop value of { 10, 15, 20 }
Vectors where each value matches a criteria @vectorprop >^a 15 ActiveX documents with a vectorprop value in which all values in the vector are greater than 15
Vectors where at least one value matches a criteria @vectorprop =^s 15 ActiveX documents with a vectorprop value in which at least one value is 15

 

Regular Expressions

Regular expressions in property queries are defined as follows:

Query Examples

Example Results
@size > 1000000 Pages larger than one million bytes
@write > 95/12/23 Pages modified after the date
Apple tree Pages with the phrase “apple tree”
"apple tree" Same as above
@contents apple tree Same as above
Microsoft and @size > 1000000 Pages with the word “Microsoft” that are larger than one million bytes
"microsoft and @size > 1000000" Pages with the phrase specified (not the same as above)
#filename *.avi Video files (the # prefix is used because the query contains a regular expression)
@attrib ^s 32 Pages with the archive attribute bit on
@docauthor = John Smith Pages with the given author
$contents why is the sky blue? Pages that match the query
@size < 100 & #filename *.gif Graphics Interchange Format (GIF) files less than 100 bytes in size

Defining New Property Names

To define properties that are not in the previous list, you must list them in a [Names] section in the .idq file. To use these properties in a restriction, sort specification, or as a retrieved column, you have define them in the .idq file, using the following format:

[Names]
#Properties that are not in the standard list
Propertyname ( Datatype ) = GUID ["Name" | propid]

In the syntax, "Name" is the property name ("Sales" in the following example), and propid is the property ID in hexadecimal. Note that you need to surround the friendly name with quotation marks, but the property ID does not take quotation marks.

For example, suppose you want to define an HTML meta tag as a property name that somebody can search for. The property you want to define is Sales.

To define the Sales property

  1. In the .idq file, under the [Names] section, add the following line.
  2. MetaDescription(DBTYPE_WSTR) = d1b5d3f0-c0b3-11cf-9a92-00a0c908dbf1 "Sales"

    The GUID number comes from the MetaTagClsid parameter in the registry, at the following location:

    HKEY_LOCAL_MACHINE
    \SYSTEM
     \CurrentControlSet
      \Control
       \HtmlFilter
        \MetaTagClsid
  3. Then, in the HTML files where you want the tag to appear, define the meta description.
  4. For example, say you want to search for all files that give sales projections for the future:

    In File1.htm:

    <META NAME="Sales" CONTENT="Projections for 1998">

    In File2.htm:

    <META NAME="Sales" CONTENT="Projections for 1999">

    In File3.htm:

    <META NAME="Sales" CONTENT="Sales in 1997">

Note   Be sure to add your META NAME tags between the <head> and </head> HTML tags at the beginning of the file.

You can now search for all files that show sales projections. Send the following query:

@metadescription projections

This query returns all the files with the word projections in the CONTENT field of the meta tag. In this example, File1.htm and File2.htm are returned.

But suppose you want to search for sales by year, for example a list of sales in 1997. Send the following query:

@metadescription 1997

File3.htm is returned.
