34 Understanding Text Search Controls

This chapter contains the following topics:

34.1 Text Search Controls

The text search control within FDA is used for both text search engines (Verity or SES). When utilizing SES as the active text search engine the following fields are hidden at runtime.

When you build the business view for the form containing the text search control, you might consider including the data dictionary items, txtscr (for verity)/sesscr (for SES) and txtsum. Txtscr/sesscr displays the score for each match returned; that is, the extent to which the result matches that for which the user originally searched. Txtsum displays the summary for the returned value; that is, the context in which the match occurred. When placed in a grid, the system populates the column automatically when the user executes a find.

Note:

You must enable the business view attached to the form for text searches using Object Management Workbench (OMW), or the text search function will not work properly on the form.This control has no unique property settings in Form Design Aid (FDA).You cannot apply logic to the text search control, so it has no unique system functions. No events fire in response to user or runtime interaction with the control. The interconnectivity level has no impact on this control.

Set Text Search Keyword System Function

To give flexibility to application developers to pass complex SES query based grammar as part of the keywords, the 'Set Text Search Keywords' system function is made available in the General category of system functions.

You can provide certain options like Match Any/Match All/Match Exact/Complex Query to the end user. Based on the option selected by the end user custom logic can be written to generate queries following SES rules and set that query to the system function provided.

Run Time Filters

If a run time filter option is selected from the filter options of a filter column a different set of operators is displayed based on the data type of the filter column.

Incremental Build

A full build results in the generation of the RSS feed for all records in the view. When a small set of records are modified (added/updated) as part of the business logic, it is not desirable to request a full build frequently. In such scenarios, an incremental build invocation can be embedded in the business function logic.

Note:

The full and clear builds are generally invoked from the Index build Definition (P95800A) application.

Below is code representing an incremental build embedded in the business function logic.

LPVOID            lpVoid;
    HENV            hEnv;
    HUSER           hUser;
    HREQUEST        hRequest;
    KEY1_F0101 dsKeySentStruct = {0};
    F0101 dsStruct = {0};
    JDEDB_RESULT    rcode;
    MATH_NUMERIC    mnSelect;
    LPKEYINFO lpKeyInfo = NULL;
    BOOL bTranStatus;
    JCHAR szBuf[1024] = {0};
    
    short nNumKeys = 1;
    int nNotUsed = 0;
 
    if (JDB_InitEnv(&hEnv) != JDEDB_PASSED)
    {
        printf("JDB_InitEnv Failed\n");
        return 0;
    }
 
    if (JDB_InitUser(hEnv,&hUser,_J("TEST"),JDEDB_COMMIT_AUTO) != JDEDB_PASSED)
    {
        printf("JDB_InitUser Failed\n");
        JDB_FreeEnv(hEnv);
        return 0;
    }
 
    JDB_TextSearchOpenView(hUser,_J("V0101C"),_J("Business Data - TEST"),&hRequest);
 
    lpKeyInfo = (LPKEYINFO) jdeAlloc(COMM_POOL,sizeof(KEYINFO)*1,MEM_ZEROINIT);
 
    jdeNIDcpy(lpKeyInfo[0].szTable,_J("F0101"));
    jdeNIDcpy(lpKeyInfo[0].szDict,_J("AN8"));
    lpKeyInfo[0].idInstance = 0;
    ParseNumericStringEx (&mnSelect, _J("1"),DEFAULT_SEPARATOR);
    lpKeyInfo[0].lpJDEValue = &mnSelect;
 
    SesTextSearchIncrementIndexing(hUser,_J("V0101C"),_J("Business Data - TEST"),TEXTSEARCH_INDEX_INSERT,lpKeyInfo,1); 
 
    jdeFree(lpKeyInfo);
 
    JDB_FreeUser(hUser);
 
    JDB_FreeEnv(hEnv);
}

The SES Text Search Increment Indexing elements are described in the table below.

Value Direction Element
hUser -> User Handle
_J("V0101C") -> Business View Name
_J("Business Data - TEST") -> Data Source Override
TEXTSEARCH_INDEX_INSERT -> Index Mode
lpKeyInfo -> Key Info
1 -> Number of Keys

The options for Index Mode are:
