Implementations

impl Index

pub fn new(base_dir: &Path) -> Result<Index>

pub fn load_semantic_types( base_dir: &Path ) -> Result<HashMap<u16, SemanticType>>

Read the semantic types list from disk.

pub fn load_concepts(base_dir: &Path) -> Result<Vec<Concept>>

Read the concepts list from disk.

pub fn concept_id(&self, id: u64) -> &Concept

Get the string associated with an ID returned from the search function.

pub fn search(&self, word: &str) -> Result<Option<u64>>

Find a word in a case-insensitive fashion. For indexes built in case-insensitive mode, this does a simple get. Otherwise it builds an automata that searches the index in a case-insensitive fashion.

pub fn search_exact(&self, word: &str) -> Option<u64>

Find an exact match for the given word.

pub fn search_regex(&self, word: &str) -> Result<Option<u64>>

Search for a word using a regex pattern.

pub fn fuzzy_search( &self, word: &str, levenshtein: u32 ) -> Result<StreamWithState<'_, Levenshtein>>

pub fn downstream_codes<'a>( &'a self, start_concept_id: u32, code_types: &'a [impl AsRef<str> + PartialEq] ) -> impl Iterator<Item = (usize, &'a ConceptCode)>
