Hello ferret users,
I have a problem with ferret dropping stored fields in the index.
Not all fields I want to store get stored, so they can be searched, but
can''t be retrieved in a search.
Index creation:
INDEX = Index::Index.new(:path =>
''/home/gregor/wisa/index'',
:analyzer => Analysis::WhiteSpaceAnalyzer.new)
SR = Index::IndexSearcher(:path =>
''/home/gregor/wisa/index'',
:analyzer => Analysis::WhiteSpaceAnalyzer.new)
Storing:
# initial creation of a lucene index
def create_index
# our central INDEX
index = FerretConfig::INDEX
# get all Companies, iterate over and index them
companies = Company.find(:all)
for company in companies
doc = Document.new
doc << Field.new("id", company.id,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("country",
company.company_group.address.country.name, Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("name", company.name,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("zip", company.address.zip,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("city", company.address.city,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("street", company.address.street,
Field::Store::YES, Field::Index::TOKENIZED)
doc << Field.new("sectorid", company.sector_id,
Field::Store::NO,
Field::Index::UNTOKENIZED)
doc << Field.new("parentsectorid",
(company.sector.parent_id ||
""), Field::Store::NO, Field::Index::UNTOKENIZED)
doc << Field.new("sector", company.sector.name,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("parentsector",
company.sector.breadcrumb.first.name, Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("districtid", company.district_id,
Field::Store::NO, Field::Index::UNTOKENIZED)
doc << Field.new("district", company.district.name,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("sales",
sprintf(''%010.4f'', company.sales),
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("employees",
sprintf(''%010d'', company.employees),
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("codesector", company.code_sector.code,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("codesectorparent",
company.code_sector.parent,
Field::Store::NO, Field::Index::UNTOKENIZED)
doc << Field.new("codesectorname",
company.code_sector.name,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("cooperation",
company.cooperation.to_i.to_s,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("lastname", company.contact.lastname,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("firstname", company.contact.firstname,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("position", company.contact.position,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("title", company.contact.title,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("salutation", company.contact.salutation,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("mail", company.contact.mail,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("fax", company.fax, Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("phone", company.phone,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("url", company.url, Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("comments", company.comments,
Field::Store::YES,
Field::Index::TOKENIZED)
doc << Field.new("products", company.products,
Field::Store::YES,
Field::Index::TOKENIZED)
doc << Field.new("state", company.state.name,
Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("investorname",
company.company_group.name,
Field::Store::YES, Field::Index::UNTOKENIZED)
doc << Field.new("investorcity",
company.company_group.address.city, Field::Store::YES,
Field::Index::UNTOKENIZED)
doc << Field.new("investorstreet",
company.company_group.address.street, Field::Store::YES,
Field::Index::TOKENIZED)
doc << Field.new("investorzip",
company.company_group.address.zip,
Field::Store::YES, Field::Index::UNTOKENIZED)
index << doc
logger.info "URL: " + doc["url"] # gets url, so doc is
ok
end
# don''t close the index, but be sure to write it to the fs
index.optimize()
logger.info "URL 1: " + index[0]["url"] # passed, prints
out
correctly
logger.info "URL 2: " + index[1]["url"] # passed, prints
out
correctly
redirect_to(:action => ''new_index'')
end
Searching:
if (@conditions != conditions)
@records = Array.new
sr = FerretConfig::SR
sr.reader =
Index::IndexReader.open(Store::FSDirectory.get_directory("/home/gregor/wisa/index"))
qp = Ferret::QueryParser.new("id", { :analyzer =>
Ferret::Analysis::WhiteSpaceAnalyzer.new(),
:wild_lower => false})
@records = sr.search(qp.parse(conditions))
end
Search results are correct, but many fields are missing and can''t be
accessed. The only fields in the results are
city, name, zip, country, mail, firstname, lastname, id, phone, fax,
street, sector, parentsector
All others are missing....
Hope someone can help me soon, this is getting me crazy.. :-/
Best regards
Gregor
