How to Allow Special Characters(#,#,!,&,(,),%) as search keyword in Sphinx - sphinx

Question

I have got struck with the implementation of allowing Special Characters(#,#,!,&,(,),%) as search keyword in Sphinx..
Please suggest me..
Below is the config file,
/* Starts */
source dbserver
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass =
sql_db = mydb
#sql_sock = /var/run/mysqld/mysqld.sock
sql_port = 3306
}
searchd
{
listen = localhost:3312
# port = 9313
log = /* some searchd.log path */
query_log = /* some query.log path */
pid_file = /* some searchd.pid path */
max_matches = 10000
seamless_rotate = 0
}
source adsearch : mydbserver
{
sql_query_post = REPLACE INTO sph_tracker SELECT 1,'ad',CURRENT_TIMESTAMP;
sql_ranged_throttle = 1
sql_attr_uint = networkid
sql_attr_uint = folderid
sql_attr_uint = createdby
sql_attr_uint = status
sql_attr_timestamp = createdon
}
index index_adsearch
{
source = adsearch
path = /* some path */
morphology = stem_en
min_word_len = 0
#min_prefix_len = 5
min_infix_len = 2
enable_star = 1
preopen = 1
}
source delta_adsearch : adsearch
{
sql_query = DELETE FROM ad where status='Deleted' AND deleteflag='Y'
}
index delta_index_adsearch : index_adsearch
{
source = delta_adsearch
path = /* some path */
}
source tmplsearch : mydbserver
{
sql_query_post = REPLACE INTO sph_tracker SELECT 2,'template',CURRENT_TIMESTAMP;
sql_ranged_throttle = 1
sql_attr_uint = networkid
sql_attr_uint = industryid
sql_attr_uint = status
sql_attr_timestamp = createdon
sql_attr_timestamp = startdate
sql_attr_timestamp = enddate
sql_attr_uint = active
sql_attr_uint = primarysize
}
index index_tmplsearch
{
source = tmplsearch
path = /* some path */
morphology = stem_en
min_word_len = 0
#min_prefix_len = 5
min_infix_len = 2
enable_star = 1
preopen = 1
}
source delta_tmplsearch : tmplsearch
{
sql_query = DELETE FROM adtemplate where status='Deleted' AND deleteflag='Y'
}
index delta_index_tmplsearch : index_tmplsearch
{
source = delta_tmplsearch
path = /* some path */
}
source media_assets_search : mydbserver
{
#sql_query_post = REPLACE INTO sph_tracker SELECT 3,'media',CURRENT_TIMESTAMP;
sql_ranged_throttle = 1
sql_attr_uint = networkid
sql_attr_uint = mediatype
sql_attr_uint = mediacat
sql_attr_uint = uploadedby
sql_attr_uint = active
sql_attr_uint = industryid
sql_attr_timestamp = uploaddate
sql_attr_uint = diskstore
}
index index_media_assets_search
{
source = media_assets_search
path = /* some path */
morphology = stem_en
min_word_len = 0
#min_prefix_len = 5
min_infix_len = 2
enable_star = 1
preopen = 1
}
source delta_media_assets_search : media_assets_search
{
}
index delta_index_media_assets_search : index_media_assets_search
{
source = delta_media_assets_search
path = /* some path */
}
/* Ends */
Please have a look at this and suggest me..
Thanks,

You need to add them to charset_table config.
You may also want to make sure you escape the query to avoid being misinterpreted as search syntax.
While there do also read up on blend_chars
