When remembering, I have learned, sort of, we have too these things:
You can remember by searching your Mind...
1) through people, events, or places...(physical)
2) through color, sounds, words, letters, styles, tones, or emphasis of their speeches...(emotional or visual)
3) through sentences, intents, purposes, moralities, motivations, aims... (intellectual)
4) through obvious absurdities and lawful inexactitudes...
5) through what kind of being it was, how collected or confident they were, how much fear was involved, how much light or dark was involved,
the time of day, the location referring to environment or surroundings...
6) through the conscience, or whether the memory touched your heart, emotion, feeling,
7) through the consciousness, is where the magic can happen, whether you were dreaming, awake, in trance, or if it was a subconscious or subliminal one, and also:

Another way to search your Mind to remember is using questions, putting to yourself questions through your own self-doing:
1) WHO was there, WHO was speaking, WHO was present,  
WHAT happened, WHAT was going on, WHAT really occurred, WHAT was said, spoken, or asked,
WHERE it happened or occured, WHERE was I, WHERE were they positioned;
2) HOW MUCH of these were involved is important, HOW MUCH you put in your memory of the occurence or happening,
HOW MUCH of you was there, or in trance, or asleep, or dreaming... HOW MUCH belief did you invest in it'
3) WHY did it happen, WHY did they speak, WHY did they ask, WHY did they do this or that,
WHEN did it happen, DID this happen before this, DID A happen first or B, or 1st or 2nd WAS this?;
4) WHICH association does this bring up, WHICH reference does it apply, WHICH lie is being converted into truth;
5) WHAT in particular was really happening for what reason, WHY did this happen this way and not another,
WHAT exactly happened for WHAT reasons, WHY did this happen, and then WHY did that happen, and then WHY did that happen, and so on;
6) WHAT did this make you feel like, WHAT did you put into your nodding, agreement, or approval;
7) HOW did it work, HOW did this happen, HOW can it be prevented in the future, HOW can the good come again, HOW can we prevent a previous evil from happening again.

Finally, you can always apply "search criteria" by also "pondering" or if necessary "ruminating" on these things...
Was the communication, or event, or place:
A) SPOOKY, SCARY, FRIGHTFUL, VIOLENT, HARROWING, FULL OF SUFFERING?
B) COLORFUL, BLAND, WHITE, BRIGHT, DARK, BLACK, FULL OF EVIL, FULL OF GOOD,
FULL OF SHIT, FULL OF PISS, FULL OF SPERM, SEXY, UGLY, BEAUTIFUL, MESSY, DIRTY, FILTHY, CLEAN
C) SMART, INTELLIGENT, WITTY, STUPID, SLOW, FAST, QUICK, RETARDED, WISE, UNWISE, IDIOTIC, SUPER, UBER, HORRIBLE, GRAND, GREAT, GOOD, EVIL
D) WACKY, WACK, CRAZY, INSANE, WICKED, HELLISH, HEAVENLY
E) IRRELEVANT, RELEVANT, SAME, SIMILAR, DIFFERENT, OBVIOUS, NOT SO OBVIOUS, CLEAR, MURKY, OPAQUE, TRANSPARENT
F) BAD, DEPRESSED, SHITTY, LOUSY, MUCKY, FUCKED UP, DOWN IN THE DUMPS, CRAPPY, HEALTHY, WEALTHY, RICH, FEELING GOOD, FEELING __, TRUTHFUL, UNTRUTHFUL,

G) BADLY, POORLY, WELL, GREATLY, MICROSCOPICALLY, TREMENDOUSLY, VERY WELL, NOT SO WELL, VERY MUCH, NOT SO MUCH, NOT MUCH, NOT SO VERY MUCH

Specifically, memory uses these mechanisms, some of the primary ones:
1) Conditionings
2) Repetition
3) Logic
4) Associations
5) Feelings
6) Intensity
7) Knowledge

--------
COUNT ( to count is to start with the thing, 1, and then count up to how many there are; also you can start with 0, meaning nothing, then 1, something, or even count the 0 if you are counting from 0 and subtract one from the sum... little tricky, but not always, and you get much better when you can start from 0, nothing, and then also start from 1, when you want to do so )
QUANTITY ( the count in a collection or set of objects or things )
NUMBER ( any thing that can be counted or "quantified" can be a number )
NUMERAL ( one number, as it appears, one numeral is 1, 2, individually )
DIGIT ( one number in a string or word of numbers )
BINARY ( based on 2 - 0 through 1, 0,1 ( 2 ) )
OCTADECIMAL ( based on 8 - 0 through 7, 0,1,2,3,4,5,6,7 ( 8 ) )
DECIMAL ( based on 10 - 0 through 9, 0,1,2,3,4,5,6,7,8,9 ( 10 ) )
HEXADECIMAL ( based on 16 - 0 through F, 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F ( 16 ) ) (then 10, 11, 12, 13 - 1A, 1B,  - 1F, 20, 2F, 30, 3F, AF, etc.)s
