Aleksa Sarai	d054adb37c	tests: add multiple results integration test Make sure we return all of the relevant results, even in cases with lots of results (larger than ENTR_PER_PAGE in the offset index) and where you have a synyonym and headword present for the same word.

Aleksa Sarai	4a9b1dae3d	stardict_lib: remove dead poGet{Current,Next,Pre}Word iterators They aren't used at all by scdv, and thus aren't tested (meaning that adaptions to the core lookup algorithms can be complicated because these methods use them but aren't tested so there's no real way of knowing if a change has broken the methods or not). Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>	2021-11-14 22:38:26 +03:00
Aleksa Sarai	6d385221d0	lookup: return all matching entries found during lookup Previously, we would just return the first entry we found that matched the requested word. This causes issues with dictionaries that have lots of entries which can be found using the same search string. In these cases, the user got a completely arbitrary word returned to them rather than the full set. While this may seem strange, this is incredibly commonplace in Japanese and likely several other languages. In Japanese: * When written using kanji, the same string of characters could refer to more than one word which may have a completely different meaning. Examples include 潜る (くぐる、もぐる) and 辛い (からい、つらい). * When written in kana, the same string of characters can also refer to more than one word which is written using completely different kanji, and has a completely different meaning. Examples include きく (聞く、効く、菊) and たつ (立つ、建つ、絶つ). In both cases, these are different words in every sense of the word, and have separate headwords for each in the dictionary. Thus in order to be completely useful for such dictionaries, sdcv needs to be able to return every matching word in the dictionary. The solution is conceptually simple -- return a set containing the indices rather than just a single index. Since every list we search is sorted (to allow binary searching), once we find one match we can just walk backwards and forwards from the match point to find the entire block of matching terms and add them to the set in linear time. A std::set is used so that we don't return duplicate results needlessly. This solution was in practice a bit more complicated because .otf cache files require a bit more fiddling, and also the ->lookup methods are used by some callers to find the next entry if no entry was found. But on the whole it's not too drastic of a change from the previous setup. Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>	2021-11-14 22:38:26 +03:00

Aleksa Sarai	51338ac5bb	lookup: do not bail on first failed lookup with a word list Due to the lack of deinflection support in StarDict, users might want to be able to create a list of possible deinflections and search each one to see if there is a dictionary entry for that deinflection. Being able to do this in one sdcv invocation is far more preferable to calling sdcv once for each candidate due to the performance cost of doing so. The most obvious language that would benefit from this is Japanese, but I'm sure other folks would prefer this. In order to make this use-case better supported -- try to look up every word in the provided list of words before existing with an error if any one of the words failed to be looked up.
