sphinxsearchHow can I use Sphinx Search to weigh my search results?
Sphinx Search is a powerful full-text search engine that can be used to weight search results. It supports a range of features, including relevance-based ranking, to help you get the most accurate and relevant search results.
To use Sphinx Search to weight search results, you need to set up a Sphinx configuration file that includes weighting parameters. The following example code shows a basic configuration file with two weighting parameters:
index my_index
{
type = plain
source = src1
path = /usr/local/sphinx/data/my_index
docinfo = extern
mlock = 0
morphology = stem_en
min_word_len = 1
min_prefix_len = 0
min_infix_len = 0
charset_type = utf-8
charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F
ignore_chars = U+00AD
html_strip = 1
html_index_attrs = img=alt,title; a=title;
html_remove_elements = style, script
index_exact_words = 1
index_sp = 1
expand_keywords = 1
weight = name^2
weight = content
}
In this example, the name
field will be given twice the weight of the content
field when Sphinx Search is used to weight search results. This means that matches in the name
field will be more relevant than matches in the content
field.
You can also use other weighting parameters, such as field_weights
and index_field_lengths
, to further refine your search results. For more information, please refer to the Sphinx Search documentation.
