iFind is an SQL facility for performing text search operations. To use iFind you must define an iFind index for each column containing text that you wish to search. You can then search the text records using a standard SQL query with a WHERE clause containing iFind index syntax.

Documentation.

InterSystems has decided to stop further development of the InterSystems IRIS Natural Language Processing, formerly known as iKnow, technology and label it as deprecated as of the 2023.3 release of InterSystems IRIS. InterSystems will continue to support existing customers using the technology, but does not recommend starting new development projects outside of the core text exploration use cases it was originally designed for.

I have an SQL text index defined like this

Index TextIndex On (Text) As %iFind.Index.Basic(IGNOREPUNCTUATION = 1, INDEXOPTION = 0, LANGUAGE = "en", LOWER = 1);

If I run a query like this:

SELECT
Text
FROM Post
WHERE %ID %FIND search_index("TextIndex",'ABC')

I get 20 results with posts containing the term ABC.

But each post can contain the term ABC several times.

Hi-

I have a SQL Query using %iFind.Highlight which returns text highlighting certain words and phrases. %iFind.Highlight seems to remove cr/lf from the returned text.

Here's my query

ClassMethod Search(pSessionId As %String, pSearchString As %String) As %String
{
set tTags="<span style='background-color:yellow;'>"
&sql(
SELECT %iFind.Highlight(Text , :pSearchString , , :tTags) into :results
FROM SSA_OCR.TempSearchable where sessionId = :pSessionId)
quit results
}

%iFind.Highlight

Hi

I've been working with SQL using an iFind index to search text. Using the %iFind.Highlight function in my SELECT statement I can get text back that highlights the found words using <b> and </b>

I am aware that using ##class(%iFind.Utils).Highlight, I can pass a parameter to override the <b> tag and use instead a <span> tag with style to change the background color of the found words.

Is there a way to override the <b> tag from a SQL statement?

Thanks

Hello All,

what is the best method for search a portion of text in a non-indexed global?

I need to implement an autocomplete kind of search, in a global of >1M registers (text type, not $lb)

Maybe the best way would be use a SQL mapped class, with 'Bitmap' indexes?

Thanks in advance!
