I am using Sphinx 2.2.11 with min_infix_len set to 3. For some terms, however, I get a really strange behavior. For example: while flor* or nat* yields no results, floru* or nata* suddenly do. Shouldn't the results that appear for floru* also appear for flor*? And, likewise, the results that appear for nata* also appear for nat*?
My index settings look like this:
dict = keywords
min_word_len = 1
min_infix_len = 3
infix_fields = description
index_exact_words = 1
blend_chars = U+23, U+26, U+2B, U+2D, U+2E, U+2F, U+2C->U+2E
blend_mode = trim_none, trim_head, trim_tail, trim_both, skip_pure
html_strip = 1
charset_table = 0..9, A..Z->a..z, a..z
Is there something wrong with my index settings, a known bug or anything? Any help is much appreciated.
