TermQuery is the most basic query and it is the building block for most other queries. It basically matches documents that contain a specific term in a specific field.
query = TermQuery.new(:content, "rails") # untokenized fields can also be searched with this query; query = TermQuery.new(:title, "Shawshank Redemption")
Notice the all lowercase term Rails. This is important as most analyzers will downcase all text added to the index. The title in this case was not tokenized so the case would have been left as is.
Create a new TermQuery object which will match
all documents with the term term
in the field
field
.
Note: As usual, field should be a symbol
static VALUE frb_tq_init(VALUE self, VALUE rfield, VALUE rterm) { Symbol field = frb_field(rfield); char *term = rs2s(rb_obj_as_string(rterm)); Query *q = tq_new(field, term); Frt_Wrap_Struct(self, NULL, &frb_q_free, q); object_add(q, self); return self; }
