Dear all ,
I just made a sparql query which functions like text search,
the query i made is shown bellow ,
=======================================
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX bif: <bif:>
SELECT ?s ?p ?o ?label
WHERE {?s ?p ?o . ?s rdf:type
<http://swat.cse.lehigh.edu/onto/univ-bench.owl#UndergraduateStudent> .
?o bif:contains '"*박근혜*"' . ?s rdfs:label ?label .}
ORDER BY ?s
LIMIT 5
OFFSET 0
but when i tried to run this query utilizing virt-jena java programming
, i got this kind of error message from virtuoso server opensource
edition .
org.apache.jena.shared.JenaException: Can not create
ResultSet.:virtuoso.jdbc4.VirtuosoException: XM028: Free-text
expression, line 1: phrase consists of noise words exclusively

I already set char encoding to utf-8 using 'charset=utf-8' on my
jdbc connection setting like "jdbc:virtuoso://localhost:1111/charset=utf-8"
and seems like all of utf-8 char encoding settings were well done. you
can check my virtuoso.ini file that i attached to this mail.
So, my question is
* how can i fix it? *
thanks in advance ,
Best regards

; Striping setup
;
; These parameters have only effect when Striping is set to 1 in the
; [Database] section, in which case the DatabaseFile parameter is ignored.
;
; With striping, the database is spawned across multiple segments
; where each segment can have multiple stripes.
;
; Format of the lines below:
; Segment<number> = <size>, <stripe file name> [, <stripe file name> .. ]
;
; <number> must be ordered from 1 up.
;
; The <size> is the total size of the segment which is equally divided
; across all stripes forming the segment. Its specification can be in
; gigabytes (g), megabytes (m), kilobytes (k) or in database blocks
; (b, the default)
;
; Note that the segment size must be a multiple of the database page size
; which is currently 8k. Also, the segment size must be divisible by the
; number of stripe files forming the segment.
;
; The example below creates a 200 meg database striped on two segments
; with two stripes of 50 meg and one of 100 meg.
;
; You can always add more segments to the configuration, but once
; added, do not change the setup.
