func UpgradeSearchOptsFromQuery

func UpgradeSearchOptsFromQuery(query string, opts chat1.SearchOpts, username string) (string, chat1.SearchOpts)

Types

type Indexer

type Indexer struct {
	globals.Contextified
	utils.DebugLabeler
	sync.Mutex
	// contains filtered or unexported fields
}

func NewIndexer

func NewIndexer(g *globals.Context) *Indexer

func (*Indexer) Add

func (idx *Indexer) Add(ctx context.Context, convID chat1.ConversationID,
	msgs []chat1.MessageUnboxed) (err error)

func (*Indexer) CancelSync

func (idx *Indexer) CancelSync(ctx context.Context)

func (*Indexer) Clear

func (idx *Indexer) Clear(ctx context.Context, uid gregor1.UID, convID chat1.ConversationID) (err error)

func (*Indexer) FullyIndexed

func (idx *Indexer) FullyIndexed(ctx context.Context, convID chat1.ConversationID) (res bool, err error)

func (*Indexer) GetStoreHits

func (idx *Indexer) GetStoreHits(ctx context.Context, uid gregor1.UID, convID chat1.ConversationID,
	query string) (res map[chat1.MessageID]chat1.EmptyStruct, err error)

func (*Indexer) IndexInbox

func (idx *Indexer) IndexInbox(ctx context.Context) (res map[chat1.ConvIDStr]chat1.ProfileSearchConvStats, err error)

IndexInbox is only exposed in devel for debugging/profiling the indexing process.

func (*Indexer) IsBackgroundActive

func (idx *Indexer) IsBackgroundActive() bool

func (*Indexer) OnDbNuke

func (idx *Indexer) OnDbNuke(mctx libkb.MetaContext) (err error)

func (*Indexer) PercentIndexed

func (idx *Indexer) PercentIndexed(ctx context.Context, convID chat1.ConversationID) (res int, err error)

func (*Indexer) PokeSync

func (idx *Indexer) PokeSync(ctx context.Context)

func (*Indexer) Remove

func (idx *Indexer) Remove(ctx context.Context, convID chat1.ConversationID,
	msgs []chat1.MessageUnboxed) (err error)

func (*Indexer) Resume

func (idx *Indexer) Resume(ctx context.Context) bool

func (*Indexer) Search

func (idx *Indexer) Search(ctx context.Context, query, origQuery string,
	opts chat1.SearchOpts, hitUICh chan chat1.ChatSearchInboxHit, indexUICh chan chat1.ChatSearchIndexStatus) (res *chat1.ChatSearchInboxResults, err error)

Search tokenizes the given query and finds the intersection of all matches for each token, returning matches.

func (*Indexer) SearchableConvs

func (idx *Indexer) SearchableConvs(ctx context.Context, convID *chat1.ConversationID) (res []types.RemoteConversation, err error)

func (*Indexer) SelectiveSync
